In late 2013, Zach Archer and I teamed up to light up the book stacks at the new Ada's Technical Books store in Seattle, Washington.

The 3,810-ish LEDs are under the control of a single BeagleBone Black and a Cyclone III FPGA. Animations are developed in JavaScript and executed in a Web browser on the BeagleBone, which makes it super-easy to update and tweak.
