A collaboration in August 2012 with Greg Friedman (thecolorofthin.gs) and Liam Holt produced a beautiful LED Wall mounted on the side of our Burning Man Camp’s Art Car. The LED wall displays scrolling text and graphic animations.
Here is an an iPad app I wrote to help drive the wall display in the desert. The iPad was connected to a beagle bone via a Redpark serial cable.
