I don't understand why Neil (the computerized etch a sketch) was required by The Ohio Art Company to include those legal statements... seems rather silly. It's not as though he was claiming he invented the Etch A Sketch.
I'd take them down if it were me.
Cool projects, though.

Wow. Everything old is new again. I did one of these back in college .... 1979. Same technology: two stepping motors coupled to the shafts. I had a stepping motor controller, which took care of sequencing the coils in response to a pair of TTL inputs: step left and step right. Controlled two motors, too. Hooked it up to an IMSAI S-100 computer (8080 8-bit processor).

Ohio art has a long history of being VERY VERY diligent about protecting their brand.
