Clever, but i tough he was going to animate it, but I suppose thats asking too much.
Mind you i had a client once that wanted an expensive mimic panel made to control ship sheet steel spraying, and came to the meeting with a sketch of the panel, and you guessed it, with his sons etch-a-sketchÂ
Seemed he had been thinking about it all night, and grabbed the etch-a-sketch, and did a doodle. Of course this was the days before electronic tablets, but pen and paper existed, DOH!
