Instructions

Set speeds of circles 2, 3, & 4 Set radius of each circle Find patterns that please you What do we call it?

Description

Sine functions, with trial and error, to make nested epicycloids. Here are some of the simplest patterns: Penguin: speed2: 1 speed3: -3 speed4: 7 radius1: 80 radius2: 30 radius3: 12 (other lengths too) Fish: speed2: 1 speed3: -3 speed4: 6 or 2 or -4 or -2 radius1: 80 radius2: 30 radius3: 12 (other lengths too) Cross: speed2: 1 speed3: -3 speed4: 5 4 lobed symmetry: speed2: 1 speed3: -3 speed4: -11 radius1: 80 radius2: 30 radius3: 12 (other lengths too)
