Default diffraction gratings

This site has some good diffraction gratings for effects.

is the site safe? or is there another good place to get them?

Also what are some cool/cheap prisms to buy?

I came across this video last night and he mentioned that site. I'm sure others have seen or done this before but I thought he made some pretty cool patterns, and he uses LEGOS.

YouTube - DIY Laser Show: The Model of the Atom

There is a 10 sheet minimum for the diffraction grating sheets and if you can get a few of each, I'll probably spend the $25. I know I've got a bunch of dc motors around here somewhere. Kinda neat.
