The firmware and build instructions have been posted here: https://github.com/somebox/DodecaRGB-firmware/
The simulator is also available: https://github.com/somebox/dodeca-rgb-simulator
There's some new animation effects added as well. I'm hoping to start soon on setup/WIFi control, accelerometer support, and creating some custom flexible ribbon cables to make assembly easier.
Too bad I'm only seeing this almost a year after camp :) thank you for sharing everything, I might try to rework your simulator to work with my dodecahedron or at least get inspired on how to get some mapped/3d stuff going.
