(computational beauty of nature: http://mitpress.mit.edu/books/FLAOH/cbnhtml/home.html).

Is on a mythic book massachussets edited.
Gives plenty of java scripts &c. that work quite well plus man & html documentation.

The scripts play simple beautiful math formulae giving nice moving images. Can it be simpler ?

Take a look and bookmark it.
