In 1999, in my Physics 534 class, my teacer, Camille Gagnon
made a demonstration with rotating mirrors and a laser which projected
nice patterns on the wall. I had been very impressed, I had decided
to do the same thing eventually.
By using mirrors fixed to dc motors, I have been able to
reproduce the same effects.
