simple SPU ray length counting trick
crappy port of an old blog entry to video. It almost feels like a badly narrated audiobook read by a voice actor that only kinda knows what he is saying. Nothing new or interesting, and with no useful animations
This is a very early variation of part of the PixelJunk Shooter 2 lighting system. It can process 4 pixels at a time and unroll to do many rays at once. It also scales to 16 pixels at a time.
