Wolfram Demonstrations Project

Some cool demos, kinda sad it requires a plugin. The medical imaging CT segmentation example is very similar to something I'm working on at the moment using javascript and the canvas tag.

Edit: quick demo for those interested (requires firefox 4 or chrome. Still in early beta :)) https://brainbrowser.cbrain.mcgill.ca/braincanvas Give it some time to load, it load 10mb of data.
