About this 3D model

I wanted a blinky thing to wear at a recent art festival. I was also gifted a 25 pixel strand of adafruit's really cool ws2801 pixels, so I printed a thing, wired it to a teensy, wrote a little arduino code, added a little bluetooth serial module, and plugged it in to a cell phone charging USB battery.
