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! Greg Garner 501-442-4847 USENET: ...!uunet!harris.cis.ksu.edu!hcx!gmg
