I have expanded on the Spiro script by adding three more types of roulettes and a couple of other functions.

R is the stator, the wheel which the rotor (r) revolves around (or inside of).
d sets the drawing point distance from the rotors center on the epitrochoid and the hypotrochoid roulettes.
Plot/angle controls how often a new point will be plotted.

I have intentionally left out the pointsToCurve command because it didn't seem to plot the graph as exact as I wanted. The script will generate quite a few points so either increase the plot/angle value or run the Path/Simplify function afterwards.

Check out these on wikipedia, it's quite interesting to read.
Epicycloid
Epitrochoid
Hypocycloid
Hypotrochoid

Updated this script to work with the new Scriptographer UI. Let me know if there are any snags.
