I remember always wanting an Etch-a-sketch as a kid. The simplicity of controlling the cursor with two knobs; horizontal and vertical. Drawing smooth curves with these two controls was an exercise in motor control. I'm pretty sure that it helped me understand circle drawing algorithms later in life. They were so much fun to play with and they were so process based. Once you drew something, it would inevitably get bumped and then your work of art was lost forever. Plus it was made by a company called Ohio Arts, which was a big plus for me as a kid growing up in Ohio.
Well, a friend of mine is involved in a project to try to bring some of that pleasure into the 21st century with an accessory to the iPad. Its Etch-a-sketch for a new generation.
