Basic spinning stage light


I'm looking for a light that I can place on the floor that would shine onto a projector screen. Something that spins with a spiral display. Either the light itself spins. Or possibly has the ability to place a filter onto a steady light and the filter spins. I'm in a band and i'm looking for something that would be strong enough to show this light display behind the drums as we play. The light and the projector screen would be relatively close to each other.
