A interesting contraption that was probably invented with the intention of becoming an amazing 3D device, but now can usually found in the 25 cent toy section in Walmart. It can be identified as a grid or pan of needles (ranging from
silver, to neon depending
on how much you want
to spend on a half-hour’s
worth of entertainment). When a hand or face
other convex object is placed
underneath, the needles rise to form an impression of said object.
