Thanks for the suggestions all of which are quite good.
This kaleidoscope is actually 3 mirrors.  It may be the way they are
positioned that makes it appear as 4 petals; I will experiment and see.
Individual rotation of pieces and artificial gravity might be accomplished
with inverse kinematics but I have research to do in this area before I can
implement.
