Spirograph kept us occupied for hours. It felt like you turned into a human computer when you put that pen tip in the plastic and pushed it around to create amazing geometric designs. Most of the time, I’d fall into a Spirograph trance until my pen would work right through the paper. British engineer Denys Fisher designed Spirograph, which first came out in 1965.
Spirograph I loved my Spirograph but was disturbed that I could never achieve the perfect results I wanted. I think this toy actually was the start of my neurotic obsession with doing things "perfect".
