Home Made Diffraction Grating Projector

Here's a pretty cool video of a project a guy did using some lasers and some diffraction grating.  He turned his bedroom into a rave, and a pretty cool one at that.  (Warning the background music contains explicit lyrics.  Why go mess up something cool with trashy lyrics???  Sheesh.)


  1. Interesting stuff. This guy could hold a party without having to pay for all the lighting and stuff. I like how it works by just shining a laser from any pen too.
