Am interested to know of any companies that will produce a design/image on to an optic, so that it projects that image on to a wall or floor when a laser shines through it. The same as those interchangeable heads that you get with laser pointers that project images of smiley faces, ufo's, hands etc. It is to be used as an advertising banner for a shop, so they can project their Logo on to the floor/ wall. Would like to know the correct term for these optic devices too, are they diffraction grating projections?????
