I am interested in laser shows an whatnot, but I am content to keep it in
this group. I do have Laser show question for anyone to answer. 
I worked on a laser show some time ago, and the only economical way I 
could come up with to make one was with two 8 inch bass speakers 
with control rods moving a mirror. Each speaker controlled one dimension,
one did X, and one did Y. Now, I see that someone (Fordham I think)
is selling a laser light show for $90.00. How are they able 
to package a laser and the controls into a cheap setup like this?
And, more important to me, How are they bending the beam? Are they 
using a mirror or Kerr cells or what?  I am burning up with curiosity
about this...,  any help is greatly appreciated!
