Okay, you know those funky thing with a million metallic blunt needles in them that countour to any object when you stick it in? If you stuck your face in, and then flipped it around, there would be the shape of your face, and once you shook the thing it would dissappear and then you can do something else! What's it called?
Anyway, I think it would be so cool to make a life-sized one. Hehe. People could push themselves into it, and then walk to the other side and see an impression of themselves. But how would clear something so big? Hmm. Can't move the bloody thing and it would be a pain to manually have to push every thing back in, there's literally thousands of the metal pins. What if I put a double piece of glass. The second one, would be attached to some sort of mechanism that would push all the pins back to the base, every 5 minutes or so? Is that possible? Hmm.
