Four mystifying glitches gleaned from this (warning: applet) fine Processing/OpenGL applet. Turns out that, on my machine at least (Firefox 3.5/OS X 10.6.1/jvm1.6), using the mouse scroll wheel whilst such an applet is playing causes a neverending stream of such oddities, pulling texture data from all over the shop (spot the eBay logo and frames from a Michael Jackson promo that I was watching earlier today). Eery, anomalistic manifestations of a half-remembered visual history.
