hey
i dont know if it is the right sub-forum to post this but hopefully i am right
for some time now i have had the idea to use Swarovski crystals as a "grating effect" for a laser and now i have finally made som test with it
i have bought 10 of these http://www.ebay.de/itm/8-Swarovski-6...item20b5bdc868
and placed them in a ring that is made out of mounting tread for PCBs the result is this
and here some test videos of it

i think that is works okey.
i am thinking that the final "grating" should be many crystals that is set on a line/tread and then lie them side by side so you get a flat surface you can projekt on to.
but let me hear want you think, pros/cons, possible alterations ??
