Trace and Blob Tracking Effect with TouchDesigner

I've been seeing this effect a lot lately and thought I'd figure out how its done and share it. This tutorial covers lots of other fun little techniques using a Cache TOP and Difference TOP to make a cheap motion detection TOP. If there's an effect out there that you'd like to learn.
