Sounds c00l, could you give me some info on the TC11 chip? Could you also 
post more on what you are planing to do, are you going to do edge 
detection? Do you plan to run your data through a nural net? I would like 
to build a real time vision system for my robot, I plan the video to a 
off board computer system.
