Descended from the classic "pinhead" toy you pressed your hand into, this clock is endlessly fascinating. The face is 3,000 pins arranged side-by-side. With each passing minute, pins lift, retract, and reshuffle to display the current time. A quiet "click" sounds with every change, and a transparent cover keeps out curious fingers. Takes 2 D batteries (not included). 8½"w x 3¾"h x 3½"d.
