That's pretty cool, brings back memories of when I was a kid (in the dark ages when all we had was geometry to amuse ourselves), oh, and outside!
Passed on the link to a few others ;-)
Both offerings are beautiful. Really liked the spirograph. I found that I could create my own 'field' for spirograph. Sorta like the
Etch-A-Sketch. I was a pro on Etch-A-Sketch. I could write cursive on it. I do not think I could be bested, except in the arena of
Etch-A-Sketch creativity.
Same for Spirograph. Figured out how to make my own custom field. Always wondered if the media was unappreciated.
I remember Spirograph - that was so much fun getting it as a Christmas gift along with those jumbo sets of colouring pens, then read up on the
mathematics; hypocycloids, epicycloids and all those other "cycloid" curves.
I LOVE THE SPIROGRAPH...sorry, trying to contain my sentimental excitement in seeing these. They always reminded me of mandalas or Celtic knots. keep
up the fun
