But contest aside, Spirograph memories! I had one and enjoyed playing with it, but I was never any good at it. I seem to remember ripping the paper a lot. The Wikipedia entry is so full of geometry mentions and even equations that my mind started to glaze over. The Spirograph I found on Amazon doesn't look anything like the old one I remember.
I wasn't very good at Etch-A-Sketch either, but I loved it. Ditto Lite-Brite. (Check out the new Lite-Brite cube--brilliant!)
There were a lot of exotic arty toys in our childhood, don't you think? Which ones did you like?
