Pixastic Image Processing Library
Pixastic works by utilizing the HTML5 Canvas element which provides access to raw pixel data, thereby opening up for more advanced image effects. This is where the "experimental" part comes into play. Canvas is only supported by some browsers and unfortunately Internet Explorer is not one of them. It is however well supported in both Firefox and Opera and support for Safari only just arrived with the recent Safari 4 (beta) release. Chrome currently works in the dev channel. A few of the effects have been simulated in IE using the age old proprietary filters. While these filters are much faster than their Canvas friends, they are few and limited. Hopefully we will one day have real Canvas on IE as well.
If you want to see for yourself what Pixastic can do, you can either check out the documentation where you will find small demos for all actions - or you can visit the Pixastic editor which uses techniques similar to those found in the library to create a simple photo editing application.

If that's not good enough, here's a quick and dirty demo of how to use Pixastic.
