Laser Vortex
I have been making the laser vortex for several years as a Halloween affect on my front porch, everyone loves the affect. Finally, this year I created a Halloween site showing others how to make one of these. The video of this can be found on http://haunted.hyperreactor.com. Its made with a laser pointer, small motor, and a mirror creating an affect similar to what you might see at Halloween Horror Nights but on a smaller scale and much cheaper.
