With a little spit and polish ("search and replace" in the Povray editor), simple cartoony renderings may be transformed into more expensive-looking sculptures, as here:

yum.

This gets us into the realm of "math + art" -- always a fertile realm (good book: 'Connections: The Geometric Bridge Between Art and Science' by Jay Kappraff -- which is just coming out in a 2nd edition this month, April 2001).

The subject i've been rooting about in for the last few years - projective geometry - a mathmatical discipline that it seems to me was the essential step toward non-Euclidian geometry/Relativity, etc - was itself a direct outgrowth of the purely artistic concerns of Renaissance painters related to perspective.

Searching on Google for 'lg3d' I come across some nice sites:

Surprised Kirby didn't mention it - maybe did not consider it relevant to this list. But Jason you might be interested that the tool that did the actual rendering at this site - Struck - is a java project that Kirby has been close to for some time and originally turned me on to - that evolved into Fluidiom, and which is continuing to evolve in interesting directions. http://www.fluidiom.com/ Unfortunately for me, the list that follows Fluidiom developments tends to communicate in Buck Fullerisms - so I don't keep up very well. But its an interesting place to lurk, nonetheless. ART
