what small motors to use?

I have never worked with something like this before but what I'd like to do is mount a couple of spinning cylinder graphics (one within another) inside a small can with a window on one side. I immagine there are some small motors or servos that could do the trick, right?

Does anyone know if there are small, high speed, low voltage, and as quite as possible, servos/motors available? Max voltage I have to work with is 12V.

BTW, this is for a wall mounted Trek Replicator project I am building. There is a pic of the foam board mock up at the end of this first post.

If you wanted to do some hacking, for high-rpm and low noise I would look into getting something like a PC case fan and pulling the motor out. The 80mm and 120mm fans always run at 12V. I have a set of Scythe fans that run at 1200 RPM's with a noise level of about 19db, which is near in-audible. The only sound generated is the 'wooshing' of the airflow but you would be taking that out of the equation since you don't need the fan.

The ones I got we're 20$ each from Newegg. You can spend a little more money on the Noctua brand fans which are the quietest on the market for that speed, at 16db I believe.

Hmm.. that's not a bad idea... PC fans. A little noise won't kill me so a cheaper fan could do so long as the graphics are not too heavy for it to rotate.
 
Your local hobby store will have plenty of small 12V motors wound to run at different speeds. If you can't find what you want in a brick-and-mortar store or a PC fan, www.digikey.com will have anything else.
