What does it take to innovate? I think it's that outside of the box thinking, that makes real innovation. Check out slide. They also have desktop clients (Windows and OSX) that do the same functionality as this flash web app, plus a little more.
If you have the time you should also check out the Yahoo! Widget Engine. This is an awesome extension of your boring Windows desktop. This is technology that Yahoo! acquired, was the same company that created the widget engine for OSX Panther, before of course Apple went and implemented their own Dashboard feature in Tiger. Still cool stuff, and it looks like the idea behind Widgets will be around for awhile now that it's multi-platform.
