Thought this might be of interest to a few of you. George Hart is including some assignments using Great Stella in his Computers and Sculpture class at Stony Brook University. Here's the link:
http://www.cs.sunysb.edu/~cse325/GreatStella.html
It focuses on using augmentation to build larger structures such as fractals.
George says the link may be taken down however once the course is over.
