Light drawings

I made some Holograms!
Just to give you an idea of the light drawings (or scratch holograms) I've been doing. More to come on my channel (with links to how it is done- technique courtesy of W Beaty) Just playing around with scratch holography to see whether I can create light drawings which give the appearance of 3D figures. The scratches are made on a piece of plastic which is then held above a light source to illuminate the images. Because of the arcs in the scratches, the image changes depending on the position you view it from. The effect is more striking in person (as each eye sees a slightly different image and this give the illusion of depth).
