The script is here: https://mohoscripts.com/script/HS_Hypotrochoid
and this is an example of its use -- many of the shapes you'll see were created using the script ... which also allows them to be animated - which is how they morph from the initial lattice to the wobbly blob that finally disappears.
If anyone has a serious use for this, I'll be gobsmacked, but it's out there for you to ignore or use as a plaything as you choose!
