One of the frustrations of the Etch A Sketch is its temporary nature. You put in all that time learning to draw and your little brother (or spouse) bumps you and it's all gone — your great art is lost forever. Rakesh Reddy has a gadget-based solution — the Remember-It-All Etch A Sketch. Reddy's gadget captures that otherwise ephemeral art and provides the ability to re-create it over and over. When the unit is in record mode, sensors in the bottom of the Etch A Sketch monitor the motion of the knobs and save the resulting motion sequences that can be repeated.
