A Spirograph within a Spirograph! This piece is an original design created by John Edmark. It works just like a classic Spirograph, except that there are two moving elements to combine: a skew ring (i.e., a disk with a hole that is off center), and a smaller disk called the wheel. This configuration results in an additional periodicity, which allows for the creation of more complex curves, and less regular drawings!
