LED Sombrero

Here is a project I started working on for our hackerspace's Halloween party but didn't finish in time. It is three 4x4 LED matrixes, one each for red, green, and blue. Each is driven by a shift register. The LEDs are from a string of Christmas tree lights. The control board has potentiometers for speed and color control.

Here is a video of some of the patterns:
