There's a cool little Greasemonkey script for Firefox that lets you animate the history of the changes of a Wikipedia article. I thought this was cool, and I wanted to use it on Wiki@Case.
If you're not familiar with Greasemonkey scripts, I'm sorry. Try Google for help.
Oh, and there was no license attached to the original code. So, Dan (the author of the original code) if you are reading this and you're really against people doing derivative works just shoot me an email.
