I'm going to fill a digital frame with only magic eye images.
Those wacky stereograms were indeed most groovy. Although in retrospect I suppose it was a bit disconcerting to have a store full of slack-jawed zombies attempting to discover the hidden images.
Just how old is Arthur?!
I mean, Sheldon is only ten and I assumed he'd had Arthur from when he was a duckling.
I almost punched out a guy selling those stupid "magic eye" posters at a street fare in NYC. I told him repeatedly that I couldn't see anything and he made the comment, "You have two eyes, don't you?" My wife at the time (the EX, now) actually had to grab my arm to prevent me from going at him.
Siliconopolitan: If you go back and read through the very beginning of the archives, Sheldon "creates" Arthur by downloading an encyclopedia into his brain. Assuming it was a relatively new encyclopedia, I think "Magic Eye" might be listed in there somewhere. And as always, Arthur tends to have his opinions on everything he knows anything about (which apparently is everything)
