It's a rectangluar piece of plastic that houses hundreds of individual metal or plastic pins. You put your hand underneath it and it pushes up those individual pins to create the shape of your hand in the pins. I had one when I was a kid and ds saw one at the speech therapists the other day and was obsessed with it.

Re: What is this toy called?
Cool! That was my ultimate goal in finding out the name...figuring out where to buy one.
