FREE: Hypotrochoid Art Set??? A Spirograph for adults! Remember the fun?!?!

The listing, Hypotrochoid Art Set??? A Spirograph for adults! Remember the fun?!?! has ended.

In the 60's, a children's toy the Spirograph, was released that created these beautiful hypotrochoids. Imagine a fixed point set inside one circle that travels along the inside of a second circle. The complex harmony of the position of the point, and the diameters of the two circles create a complex looping track. It's beautiful, but it's math!

Included in the Hypotrochoid art set are:

Two Hypotrochoid templates (outer circles)
Six gear circles (inner circles)
Red Green and Blue Pens
Convenient metal traveling tin
