Pretty cool. I wonder if a webcam would work - with some different optics infront of it. I might have to pick one up and give it a go.

Ryan..I'm sure. I used a 55MM lens off a Minolta 35mm film camera. I used the cover plate that locks to the bayonett on the lens..and drilled and attached an EP holder to it. Then slid the camera that has an 1 1/4" barrel on it. I had to adjust the focal length and there you go.
