A fun science project kit
I have one of these and it is just fun. It is a plastic front and a AA battery motor assembly and circuit board on the back.
The circuit board has an EPROM with a pre-loaded BBC "checkerboard" test pattern ready to go. You can drive it with a CD, but mine was never very stable with it.
The pic of the pattern shows the hot spot, but it is better than it looks in the pic. The camera hates it, the eye does better. Give it a try.
