A simple sketch that I made that converts the intensity of pixels from a webcam image into a Z value and draws horizontal lines to make up the image.
I decided to make this after being inspired by the recent radiohead video (house of cards) and realizing that I probably won't ever be able to get hold of a 3D laser scanner...
** Apologies for the pink- in the video. The lines are supposed to be green, but that seemed to happen after the vimeo conversion **
