Cool things done with light
Adam Frank is a creator of light based objects. His gadgets or items or what ever you might call them show light is some very interesting ways. I was amazed veiwing his web site. His objects refect light, absorb light, project light, and do really cool stuf with light. You may put any one of his projects on my Christmas wish list.
I can’t describe the visual effect so just vist his site and see for yourself.
