A Spirograph is a geometric drawing toy that produces mathematical roulette curves of the variety technically known as hypotrochoids and epitrochoids. It was developed by British engineer Denys Fisher and first sold in 1965
Well I don’t know much about hypotrochoids and epitrochoids but I made this using what I had learnt in Pre-College. I first made this in Excel by making a Graph. Then in college, after learning Flash made this in July 2011.
