I played around with this funny thing yesterday. The thing can make shapes of whatever you hold it against by having hundreds of small nails which can go back and forth. Nobody could tell me what it was called or where I could buy it. Maybe someone from here can tell me that. A link to something on ebay or just a name to search for would be helpful.
I took two photos of the thing here:
