Volver is a 3.75 inch square LED matrix that will display over 1600 unique patterns. Designed by members of Image Node and Disorient, it is a fundraiser for burning man 2009. While it is certainly less colorful than its older sibling the Nodeblinky, it features 8 more LEDs and a bit smoother and faster graphics. Volver can be picked up as a kit, or fully assembled from their site. Just like last time, you don’t have to buy from them. They freely offer the source code and schematics.
