Finding a baby mobile turning mechanism

[Adoptamom_II]

I need the mechanism that turns a baby mobile (you know - that thing you hang on the side of a newborn babies crib).

Any idea where I could find a reasonably priced source for that mechanism or a similar turning type mechanism that is either battery operated or wind up?

Any idea what the real name for that mechanism is so I could practice my googlefu?

I was going to suggest a thrift store for an old mobile to junk for parts as a faster and cheaper solution.
