Retro Thing has the history and some links to these amazing animated records, seems like you could do this with a CD player if you modded the heck out of it (would be worth it!) or just get a record and start experimenting... - "These were cardboard children's records with the animation printed right onto the disc itself... The Red Raven included a little mirrored device that you pop onto the turntable's spindle that reflected the animation in such a way that while the record plays you get to see a little cartoon." - Link.
