...if you make a loop/oval out of ice tiles, and place one conveyor tile in the loop with a reflector on top of it, and then place three more reflectors on the ice tiles (spaced evenly, but not on a curve or right before one), that all four reflectors will slide up right next to each other and begin to spin the loop endlessly...

I haven't been able to get more than four reflectors to survive this experiment.

Here is an example of what I mentioned above-
