I finally got around to getting my 2004 paper "Stella Models" online. Here's the link:
http://www.software3d.com/StellaModels/StellaModels.php
It was published in Symmetry: Culture and Science, Vol. 13, Nos. 3-4, p391-399, 2002.
The journal was running years late or something, so it was back-dated to 2002, even though it was released in 2004.
