Here is a good write up of what the Etruscan Venus is about. In the two decades since her birth there has appeared a lot about this singular Klein bottle, not all of it as historically accurate as one might wish. Google Pagerank's inability to judge content over popularity just proves we have long way to go before the Web replaces Paper.
Sadly, the World Wide Web is impermanent and volatile, and links break. Someday I'll have time to repair this page.
Here is a streaming video of the Etruscan Venus by George Francis, Donna Cox and Ray Idaszak.
Our postmodern Venus also stars in an award winning video by Donna Cox, Venus and Milo.
Here is the NCSA Video Library where you can find more streaming videos.
