there is a mobile with a slightly darkened image on a jagged circular hard plastic. when you spin it around, the image moves in motion. i.e., you look onto this image and you see a man on a bike, but when you spin it, the image shows him riding the bike. looking close up on the image i see the image (i guess) sketched on the hard jagged plastic more than 4 times in sequence. what is the name of this craft called?
