Processing Visualization Language Ported To Javascript
Manfre writes "On his birthday, John Resig (creator of jQuery) has given a present to developers by releasing Processing.js. This is a Javascript port of the Processing Visualization Language and a first step towards Javascript being a rival to Flash for online graphics content. His blog post contains an excellent writeup with many demos."
JS interpreters are not optimized to do image manipulation, DOM updates, etc. Now this isn't to say they aren't moving in that direction, but as of now they are atrocious at these tasks.
Flash is a completely separate environment from the browser, is vector based and inherently performs animation better. Right now it's always faster(CPU %) to do an animation in Flash then it is to do the same animation in JS.
