Move Instanced Shapes on Spiral Path with CHOPs
To move instanced shapes on a spiral path we can use three PatternCHOP one for each position value. 
With sine and cosine for the txand ty or tz values we can create a two dimensional circular shape. By adding a PatternCHOP with Type Ramp for the 3rd dimension we can stretch it out into a spiral path.
Changing the amplitude of the sine and cosine PatternCHOP we can change the diameter of the spiral. 
The Number of Circles defines the frequency / the amount of rounds.
