I've been collecting nice little geared Moters (5v) out of disc driver I've been harvesting diodes from. Seem great for something like this. May try my hand

don't know about those^^^
but for total control you need speed control-& direction option and OFF.(DPDT)-- if those don't have that-- I would skip and go with motors that can.. I grab every Poliroid One-Step I can buy (at tag/yard sales etc) as long as its no more than 1$-inside a swell VDC 3v motor and keystone FSM thin but fairly easy to cut- lots of plastic gears good for attaching motors to mirrors... other Polaroids have useful stuff inside but often cost more-- DUH! film for them is not an easy find...

I just built a simple single color spiro. I used a combo of old brushed RC motors and some motors pulled out of a inkjet printer. For my FS mirrors I cut small squares from a hard drive platter, JB welded them onto the motor shaft with pinion attached. After the JB weld hardened I spun the motor and used a carbide Dremel burr to make the square round.

I was suprised at all the patterns that it made!
