This is a Grasshopper definition I made earlier this year that allows the user to generate 3D Supershapes. I started playing with it again in the last few days to test out the "Save state" feature in the new 6.0018 release of Grasshopper.
The definition plots a set of UV points in 3D. The surface by points component is used to create the supershape.

The definition works with the latest release of Grasshopper (6.0018)
(I've tested it with GH 6.0018 on two Windows XP computers with Rhino SR4 and SR4b)
If anyone does anything cool with it, let me know and I will post it on the blog.
Enjoy!
