the stonetek ones are sheets of plastic though

So? They're still decent diffraction gratings...

i never said they were crap

by the way a few days ago i took apart and found a few line generating foils, and the backlight screen was a line generator too. you can get it from here:

I have two of Nova's plastic diffraction gratings, the rainbow ones with 13,500 lines/inch on them, and they work very well, but I imagine glass/crystal would work much better.

I have an old 5mW red laser that you could make into different shapes. It wasn't made for high powered lasers though so when you put a green through it you get this:

It can still put the shape on houses kinda far away. But I can imagine a high quality batman one would work very well. Someone here could definatley make money off that one!

This is what I had: http://scientificsonline.com/product.asp_Q_pn_E_3081864

It has many sybols and shapes. Maybe I could find out who makes it or something. Could at least E-mail them about, couldn't hurt.
