Back when I was a kid, I used to play with those pin art boards, where you could stick your face in, or any other object, and obtain the shape of this object imprinted on the surface of the board.
In remembrance of those good old times, I present: the Pin Clock! This battery operated clock uses hundreds of pins to display the time in 3D. The pins automatically reshuffle themselves every minute to display the current hour and minutes. It retails for $59.95 on Amazon.com.
