I came across the a USB powered strip of RGB LEDs that I wanted to try out for GI on the WOZ
The materials:
20" LED Tape Light ($8.13) - http://bit.ly/1iH2JDW
6.5" USB extension cord ($.88) - http://bit.ly/1kslNIT
EDIT: updated links and the prices went down
The results (please excuse my camera work/quality)
The videos in order show the following:
WOZ without LEDs on
WOZ with LEDs on
USB Connector (other end is plugged into the WOZ computer)
LED lights changing color
