There are atleast 3 diffraction gratings inside projectors, thats where I got mines, I must say they are pretty cool. I might buy some more when I get some time and money.

IF you happen to get the plastic sheeting kind - like the (awesome) stuff I sell....fold it gently in half, and shine your laser through it again....it doubles the effect - fold it in 4ths - viola ! Pretty neat stuff !

Do all line generators go like . . . . . . . . . . . with lots of dots or do some actually have a line like _____________ that?
