Pinpoint impression toy

[Ernesto]

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 or some other [convex] object is placed underneath, the needles rise to form an impression of said object.
