i was joking with some friends with my new laser
and i thought about using those silly gratings u get with cheapo red lasers, like the ones that project a nude woman onto a wall.
well
i was wondering if it was possible to MAKE a grating? or do i have to order a special one to a factory
if anyone knows, please help
PD: for example, i would like to make a BATMAN symbol grating
