Back in 1997 I made a stereo webcam for keeping track of my dog, Gromit.

I was rolling through some archives and found an image from January 1998. It used two Logitech golf-ball cams and a bunch of ad hoc software. Pushed the frames to my machine at OSU Vision Laboratory. I’ll see if I can find some photos of the rig, but, I dare say it was one of the first stereo webcams ever. (Update: found some)
