testing out a brightness tracking script in processing which finds the brightest pixel and puts a huge yellow blob on it. it only seems to work well in the dark, when i tried it out earlier in the day it kept jumping to bright pixels generated by my bright window. might be a bit problematic if i use brightness in my final piece, it'd have to be pretty dark to work.
Whilst researching the BlobDetection library i found puppet show a processing / unreal programmage that uses colour recognition to control a character in an unreal environment.

(you can tell they're cool, they play guitar hero)
here's a video of it in action and how it works:
I'm hoping after some rooting around in their code i'll get colour recognition working.
