One concern I have for the set up is that at any given point the four discs might be at the same position every time they pass a beam. So they will always project the same pattern as it is rotating. Which wouldn't look bad at all , but to add a sense of dynamic movement you might want to think about a diffraction grating between the laser module and the lima wheels.
One other thing to think about is are the smaller wheels turning at a 1:1 ratio with the main wheel? My thoughts are they will be going significantly faster and may not project the slow transition between the effects as well.
Having said that I am glad I subbed and will be watching this project closely, sounds like an awesome idea!op:
my lumia projector (the one in the pic i posted) has two wheels that counter rotate *very* slowy and slightly different speeds (~.2 and ~.3 rpm). the patterns repeat, but the interval between cycles is quite long.
