Roman Kogan, a student at Stony Brook University in New York, has developed a simple program that turns your webcam into a scanner camera of sorts. Above is a photo I did with my Macbook’s built in webcam. It works by taking one pixel line at a time and arranging those slices in a line to produce the image. Thus one dimension of the image is spacial, and the other is temporal. It was buggy on Macs before, but Roman seemed to have fixed the problem.
Give it a try for yourself by checking out the site Roman set up.
