This guy designed a toy camera that he put on his cat that would take
periodic pictures (elsewhere in the site he tells how he deisigned it).

It is utterly fascinating to me the pictures this cat 'took' over several days.
There are things a human being would probably never see.

Check it out. The camera listed looks very groovy too..........$20 with a 1.3 megapixel resolution
manual focus and the ability to take webcam pictures but fits in your hand. I'll order mine tomorrow.
