Did you ever dream of acting in a screen saver? Now you can, with SightSaver...but don't bother appearing a bit distorted! SightSaver is a little Cocoa-hack in which I directly feed the images captured by the iSight camera into an 3D-OpenGL texture. The only use I've got out of it until now is to project this animated texture onto a rotating torus. Silly, heh? But fun to look at.
