You might not remember the Tron Recognizer from the video game Tron, but in the movie it was the slave of the master which went around trying to destroy the tank and the light bikes. I was really excited when I found it on Cafepress, so that probably tells you how much of a geek I am. I just need to find the light bikes now and I will be happy!
