This is an L.E.D illusion mirror. It is set up in a dark room so that we may see it’s full effects. The lights that are set up on the mirror are blue and round. There appear to be 6 rows of these lights that get larger toward the top, however, that is just part of the illusion. This mirror is a very cool product and I could see how someone would get many hours of enjoyment out of making one.
