You know, first thing that came to my mind when I saw the title of the news, before even opening it, was that I should post a link to teddy! This was a land before time of zbrush and mudbox. It was a land of new horizons with nichimen (ex symbolics graphics division) leading the way of the new technologies in modeling. That was a great time to witness. And to think of LISP being behind it all...
I still have a soft spot for Teddy, though, which is a solid modeler with a great gestural interface:
