Clean up.

Spent the last few days cleaning up some old broken blog posts. Used MarsEdit 4, which made it a breeze to yank out old flickr-linked images and replace them with local copies. Sweet.

Winter = creativity. 

As is usual for me, Winter is a slow period for the sculpture business. Rather than spend my time carefully categorizing my favorite local brews by IBU and hangover severity, I’ve been flexing my creative musk oils—er, muscles— with a bunch of 2d work. I picked up one of the big iPad Pros, and it has been a revelation. I’ve used Wacom tablets for years, but have never had the experience of drawing directly on the display surface. Well, not with the level of precision that Apple’s Pencil provides. If you have any desire to draw digitally, do yourself a favor and try one out.

These designs are made with a vector drawing app called Assembly. As the name implies, it primarily involves assembling pre-made shapes into compositions. I enjoy the challenge of resisting complexity. I add textures with a variety of other apps, and run the final design through an app called Percolator to give them the packed-circles look.

Also have been doing some sketching on the iPad. Nice.


A few of the things I’ve been up to since my last posty.

The Rotary Wheel is installed in the Rotary Plaza in Little Rock.

And so is the Mockingbird Shade at the Children’s Hospital in the same city.

Split Infinitive, re-worked.

I designed this piece way back when Sketch-Up was my main software for modeling. I was pretty happy with the way it turned out, but over the course of its fabrication the first time around, I discovered a pile of things that could have been done better to yield a smoother and less laborious process. Chief among the changes was making the thing symmetrical vertically, which enabled me to eliminate two entire butt joints in the sheet metal, which means significantly less grinding – which means a much happier Humble Narrator. I used my original Sketch-Up model, importing it into Rhino so I could have a starting place for the geometry:

Mesh edges from Sketch-Up.

After a whole bunch of mucking about and snapping new construction curves to that stuff, I was able to get a cleaner version that had the added benefits of being easier to fab AND better aesthetics.

Fixed up in Rhino – and natively on my Mac in the Rhino Beta for OSX.

From there, I used Rhino’s Unroll command and some patience to arrive at a 2d pattern, ready to send off to the laser for cutting out of stainless steel.

Unrolled surfaces of the 3d model, colored for identification.

The Gallery below shows some of the initial stages of the assembly. I made a gumby little wooden jig to bend the tight inside curves; the outside curves bend against the “sides”, so don’t need to be pre-rolled.

I LOVED the piece with just the sanded metal surface, but this one is actually sold, and the client wanted a yellow powder coat. Yellow? :– {

Turns out, yellow is SPECTACULAR on this thing. The first image above shows the piece fresh from the powder coater, followed by some shots of the edges being filed back to reveal the shiny stainless underneath. I love the way this iteration came out. Hopefully my clients feel the same – shipped it off a while ago and wondering what they think.

Dutch angle with Japanese maple. Artsiness.

PS: I posted quite bit about the first iteration. Some linkage:

I’ve been working on another edition of my “Event Horizon” piece. The concept behind the sculpture has to do with the theorized existence of a gravitational border around a black hole beyond which nothing can escape. I wondered what it might look like to see something torn apart but not completely consumed by the black hole; what might the remnants look like as they were spun off into space? I thought it might be stylized into something like this:

Imagine my surprise when I stumbled across this video, showing a Red Giant star being ripped apart by a massive black hole at the center of a nearby galaxy:

Fun Weekend.

Got to hang out backstage at Red Rocks with the cool kids from Devotchka. Wow, chapter 1.

Sold out show for Devotchka and the Colorado Symphony Orchestra.

Followed that up with a trip to the Denver Botanic Gardens to check out the Chihuly glass work there. Amazeballs.

New Studio.

Ren found a great space for me behind the local Whole Foods. It was set up as a storage space for a TV repair guy – an old-school tubes and cathode ray sort – who held the space for almost 30 years. Sadly, he died a few months ago, leaving behind a shop that worked perfectly for him, but not so well for me without some extensive modifications. The overall dimensions of the unit are pretty decent, but he had cordoned off several areas for his needs – where I am in need of one big space, with plenty of ceiling height, so I can have room to move around as I fabricate larger pieces. My landlords gave me the go-ahead to make any modifications I needed, so: Let the destruction begin!

Here’s what I started with:

This whole “room inside the room” had to go. I wanted to try to salvage and reuse as much of the lumber and electrical as possible. It turned out that, in many cases, the carpenters who constructed the room had done >too< good a job; glue and ring-shank nails probably seem like a good idea if you want to “build it to last”. But the reality is that nothing lasts forever, and planning for the guy who has to make alterations to your construction may be a wiser ecological move. I had to tear some of the framing members (especially the stair stringers and treads) literally to splinters to get them apart, forcing me to put them in the firewood pile instead of the build-something-else-with-this pile. I grew up with this “we build things right, to last” mindset, handed down from my Mom’s dad (good ol’ Otto Reimer, BTW) and from my father as well – and you can still drive around Loveland and see some of the houses we built, standing the test of time. Yet the fact of the matter is, there will come a time when those buildings will need to be altered or torn down, and the construction techniques we used will make reclaiming the materials WAY harder than had we planned for this eventuality. Lessons, always lessons.

3/4 inch plywood, stapled and glued down. Staples every 3″-4″. Had they used screws and no glue, I could have re-used every sheet. Instead, Hageman’s ground them into chips. Pity.

Yea! First sheet off. Only 9 more to go.

I’ll save you most of the boring rest of the story. I did manage to hang some new lights before I tore out the nice platform for accessing the ceiling of the unit.

Some more dramatic progress shots:

And here’s the space, modified to suit my demented needs. Note I left a small bit of the former room for a storage platform – we were able to move out of our storage unit, too. Bonus.

A bit cramped, but very workable. Now – to work!


So, this:

“HiveMInd” on site

“HiveMind” in Fort Collins, Colorado

When I proposed “Growing Together” for the Poudre River Public Library here in Fort Collins, I’d also included an idea for an outdoor piece that related to the idea of the hivemind. The committee liked it so much, they elected to work towards raising the money to purchase it (“Growing Together” was a percent-for-art portion of the new construction.) It took a while, but they managed to get the funding together. It turned into a really fun project, requiring that I stretch a bit and recruit the services of some outside vendors that I hadn’t worked with before. I’ve been growing more and more frustrated with the negative impacts welding has on the sheet metal I work with – the heat tends to warp and distort the sheets, plus the welds themselves need cleaning up through grinding and polishing. “HiveMind” ended up still requiring quite a bit of welding, but the key parts that make the design “sing” are pure assemblage. I’d like to push this idea even further in the future to eliminate welding altogether – the idea of not having to chase any welds coupled with the problem-solving involved intrigues me no end.


A hive mind is the emergent property of apparent sentience that arises from the behaviors of a colony of individuals. Just as your neurons, without individual intelligence, interact as a unit to become a brain, so one can view a hive of bees or a colony of ants interacting as a unit to become a mind.  The whole has behaviors, memories and characteristics that could not be predicted by studying an individual. The idea that the behaviors of the individuals in a society, on a planet or on a network, might interact as a whole to exhibit behaviors that were beyond the ken of parts.

“HiveMind” consists of a central monolith with two sides faced with polished stainless steel hexagons. On one side these hexes are flat, in essence creating a mirror. The opposite side has hexagons which are rolled to make each one slightly convex – also creating a mirror, but one where the reflected subject is broken up into multiple images. I’m hoping to orient the piece such that the viewer sees oneself reflected as a whole, with the library in the background – symbolizing ones integration into the community formed around and within the library. Moving around to the other side of the sculpture, one then sees multiple reflected images, symbolizing the individual members and highlighting their importance to the culture of the library. Thematically, the sculpture is striving to accentuate both the collective community of the library and each person’s importance to that community.


After discovering the wonders of Radiant Acrylic, my brain was sparked by all kinds of ideas for exploiting its qualities. While goofing around with a remnant from the SoundSpindle, I noticed that the dichroic effect was even more pronounced when the sheet was bent – the angle of incidence at which the light strikes being the main driver of the color shifts. I also liked the lightness and freedom of hanging forms from the ceiling, eliminating the grounding structure of a base and letting the piece “float” mid-air. If you follow my posts at all – or just have a quick look around – you’ll probably notice I have a bit of a “thing” for hexagons. Can’t really explain it other than to point out that, geometrically, you can’t get much prettier than the hex. So, I used a hexagon as my starting point and lofted a tapered solid from it, ending up with what is essentially a truncated hexagonal pyramid with curved sides, mirrored across the Z axis – like so:

Hexamabob starting shape

Each face of this form was then “unrolled” to yield a flat pattern that could then be cut out with the laser, plus some kind of supports would be needed to hold the whole thing together. I ended up using SolidWorks to handle this stuff, using the sheet metal tools to create the actual sheet metal parts as well as the acrylic. The really impressive thing about SolidWorks is its parametric nature: I can go back into the file and change just about any parameter – overall scale, ratio of width to height, etc. – and the whole design updates smoothly, including the flat patterns. Saves TONS of work if I ever decide to produce other sizes or need to make changes to the material thickness or fasteners. Below is a gallery of images that shows some of the design process.

I didn’t think to get any shots of the actual assembly process, but the last image in the gallery does show how the digital design becomes real-world parts. I’ll get some more in-progress shots on the next one.

I really like this one – its simplicity and the level of impact for the amount of material used is pretty spectacular. I’ve gotten lots of good feedback, and it’s prompted me to try something new as a result. Stay tuned!

Hexamabob – finished, on black


I came up with what I thought was a pretty good idea for a proposal for the New Mexico School for the Deaf (which I didn’t land – more on that later). I had wanted to somehow engage the student body itself in generating the concepts, and thereby the forms, for the piece. I was messing around in Garageband when I noticed how the waveform being generated by spoken word portions of the playing track were pretty interesting when viewed as silhouettes – much less staccato and fuzzy than the instruments. Being a complete 3d software nerd, whenever I see interesting silhouettes, I always want to try to manipulate them somehow into three-dimensional forms. Tracing out the waveform’s outer edge and then spinning that outline around a central axis expanded the shape into the 3rd dimension while still allowing the original sounds to be readily evident. I thought, “How about having the students supply me with a bunch of words and phrases that have meaning for them, and then record these sounds to drive the shapes!”

I loved the idea, and everyone I bounced it off of said, “Cool!” before punching me for hurling ideas at them.

In a synchronicity that may seem hard to believe, while researching further on sound-derived sculpture, I happened across this Instructable for making bracelets or necklaces using the exact same technique I’d come up with for the sculptures. I felt a little nervous about “ripping off” the idea, but the fact that I’d arrived there independently, coupled with the waveform technique being freely available on the internet in a format MEANT to be reproduced, quelled my fears. Onward!

It wasn’t difficult (the link is right there on the first page of the Instructable) to find the author of the post: David Bizer, a jewelry designer in Berlin. I looked around on David’s website, and found this picture:

Lookit all them colors!

“What Devilry is this!”

The material just blew me away. Apparently, I like shiny things. Searching around the web, I was unable to pinpoint just what it was – so I sent David an enquiry. He wrote back immediately, calling it “Rainbow Acrylic”, which he gets from the online laser cutting shop Ponoko. I ended up having to contact Ponoko’s material guys, who informed me that the material is by Acrylite, and it is officially called “Radiant Acrylic”, and that it is not available at the US Ponoko shop.


I hunted down the Acrylite website and was able to get my hands on some of the stuff. The NMSD proposal required a maquette, so I elected to fabricate a mock phrase, “I am not broken,” to convey the idea. Below is a graphic from the proposal that illustrates  how this all works:

NMSD Proposal Graphic

After much cursing and fiddling about in damn near every software package I own, I was able to produce some usable patterns for my laser dude, Bill at Wesco Laser. (Caution: Auto-playing sound and animation, but NotNSFW linky.) Here’s how it looks while being assembled (please ignore the pretty towel):

I am not a photographer, nor do I play one on TV.

That there is some purdy stuff, yo.

Which brings us to the point of this post – I have a new material in my arsenal! (Heh heh – he said “Arse”) Radiant Acrylic is awesome. I love it. Even though I didn’t win the job for the New Mexico School for the Deaf, I ended up with a net positive. I went ahead and made some other forms using this technique, utilizing actual music to drive the waveform. I’m really excited by the possibilities here – any sound can be used, from someone’s name, to a poem, to a favorite piece of music. This one is “Spring” by Vivaldi, shot by the always-awesome Jafe Parsons:

You may have noticed a tapering off of posts here – well, that’s due to the fact that posting is huge pain in the ass on Squarespace’s system. Tumblr has gotten much better stability-wise, and it makes posting a frictionless joy. “Get to the point, Mark!”: Go check out my Tumblr

Growing Together.

“Growing Together”
Just installed yesterday at the Poudre River Public Library right here in Fort Collins.
From the original proposal:

“Growing Together” is a sculptural allegory depicting three simple, sweeping shapes that diverge and merge as they gain in scale. These forms and their interactions metaphorically speak to the path that people take as they learn and grow, with the intersections representing our reliance on each other and institutions like the Poudre River Public Library to enable and encourage this process of growth.

More pictures of the fabrication and install.


Beginning – from the beginning.

What, two blog posts in a week? Am I feeling OK? Yep – just finally have some time to sit down and update things. Here’s another piece I got done over the summer:


I batted around the idea of titling this one “Just After the Big Bang” or “Origin of the Universe” or some such – but I decided to simplify. Nonetheless, to me it represents what the Universe could have looked like just a few Planck Time units after the Big Bang, with a lot of artistic license thrown in for good measure. I started with a simple egg-shaped surface in Rhino, then used the built-in Paneling Tools to array the hexagonal base unit over said surface. LOTS of flailing around and reiterating until I finally got something that would work. One complication of this particular design that normally doesn’t occur in my Rhino work is the thickness of the material – because it incorporates repeating components, the thickness of each one must be allowed for in order for the pieces to properly form the correct final shape. This is one area that Rhino struggles in, as it employs surfaces that are zero-thickness rather than solids with volume like real-world sheet metal. I imported the surfaces into Solidworks and added the appropiate thickness, but then had to pull them back into Rhino to produce the correct patterns for the laser cutter – Solidworks is just too rigid to allow my crazy shapes to be modeled with its sheet metal tools. Go figure. Anyway, this is what I ended up with, pared down to a quarter of the whole form:


As you can see, each strip (color coded for clarity) is just slightly different from its neighbor, necessitating careful labeling in order to keep it all straight. It also takes someone who can handle simple arithmetic, like how many quarters it takes to make a whole – which I goofed on and had to order the other half after the fact. Oops. 2 X .25 is NOT 1. Below is the unrolled strips – half of them, anyway.


Evident on these strips are the bend lines, with mountain and valley folds color coded cyan and magenta. Keeping that sorted in my head was a source of continual stress. I ended up modifying a drill press vice to simplify bending the strips. The basic procedure can be seen below:


Once I had all the strips bent into these goofy accordian-like shapes, I was able to clamp them together and get a pretty decent tack with the TiG welder to glom them together. This was by far the most labor-intensive sculpture I’ve made so far.



As the strips went on, they gradually forced themselves into the desired egg-shape. I did have to tweak and clamp and swear and complain to compensate for small erors that grew larger over time, but it actually formed up pretty well.


This one was a real learning experience, forcing me to come up with all kinds of new techniques and procedures to get the job done. In other words, I loved it.

The frame you see in the top picture above is just for displaying “Beginning”; I envision this as a hanging piece in an atrium, stairwell, or foyer. The same techniques I empoyed here could be used on a much larger scale. I’d love to give it a whirl.
