I have a bathroom cabinet shelf, though it's tempered and difficult to cut pieces, it works well, However, if yours is not doing much, you can run two thicknesses on different motors for improved effects. Vary the distance between them also. If one glass doesn't spread the beam much, having the second glass further from the first will widen the entire pattern. Just having a crystal vase on a rotating platform, in front of a screen, can yield good effects as well. AND, DON'T forget to point your laser into your nearest diamond ring !</p><p>Also great is the motors and mirrors "Laser Spiro Graph".. The mirrors are mounted "almost perpendicular" on the motor shafts (not like a tennis racket, but like a wheel): THe trick is getting the mirrors as close together as possible. It you use fans, instead of bare motors with shafts, this is difficult. The more mirrors and motors you can bounce the laser off of, the better.

http://www.instructables.com/id/DIY-Laser-Spirograph/</p><p>I started doing Laser light shows in the mid 80's using the Radio Shack Color Computer and two Galvos salvaged from a thermal strip chart medical monitor. All the software was my own, though I was coached by one of the ILDA members. I eventually developed some sophisticated SW for drawing images on the RS graphics tablet and animating them and choreographing them to music. While I concentrated on the graphics of the "dot-to-dot" drawing type, I also used a model airplane (PWM) servo to move a couple of different lumia effect glasses into the beam.
FYI: I have complete information on the math and computations for this on my site,. Images are drawn, saved in a library and displayed with commands in RAM that determine the size, location and rotations of each image.
However, my SW is NOT portable to other platforms. The higher level routines for drawing images and doing the choreography are in RS Basic and the actual "Display Processor" that runs a show is in 6809 .MicroProcessor Assembler.</p><p>I have also seen some pretty good things done using the sound card output D to A's of a PC on YouTube. Can't seem to find any good ones just now</p><p>My INFO: http://k9dci.home.comcast.net/site/?/page/Laser_Graphics/</p><h2>ILDA: http://www.laserist.org/</h2><p>Cheers, ScienceAdviserSteve

Heading towards buying a proper Laser Show Kit.</p>

We built a stand with a motor spinning a plate. The motor was precisely controlled using a PWM control chip. For the laser we used a 100mW blue Argon laser that we would shine through various vases with twists and turns in them. With the laser going through the glass we could get effects that looked like fluid flowing on the walls in slow motion. The PWM chip had a dial so we could control the speed of it. In addition we had a dual axis laser writer showing different items on the wall during the show. All and all it was a fun project and we learned a lot about the electronics and the programming to control it.</p>
