The frames were made from 2x4's, ripped down, then cut with a dado groove down the middle to hold the screens in place.
The screens themselves were cut from 1/4" MDF on a friend of mine's 4x8' CNC router from a design I had made using Blender's Mechanical Gear generator. The gears were rendered, imported into Adobe Illustrator CS5, LiveTraced, and combined using the ShapeBuilder tool. Then the whole mess was exported as a .DXF.
The frames received a coat of flat black spray paint, while the screens were treated with Hammered Copper spray paint. I relied on the porosity of the unfinished MDF to soak in parts of the paint. Because of this, you don't get the intended hammered metal effect; instead, some of the silver and some of the copper soak into the material, giving an aged, partially rusted look.
This is intended to be used as a backdrop for art events. I'm currently working on some hangers that will compliment the screens so that I can hang up some of my work without taking up precious table-space.
Just think, if I win the contest, I can produce more of these....
