Looks like this has been around for a little while, but I just had an opportunity to play with it tonight.  Simon Ferquel has written an Mac OS X like Expose application for Windows Vista.  I just installed it and although it takes a few moments to start up, it works great.  Just select the F9 key or click in the top left corner of your screen to launch after initial startup. 

You can download here.  It is running great on Vista RTM for me and is a great addition to Flip 3D. :-)  Really cool use of the Desktop Windows Manager API.  Expect to see much more cool stuff like this as developers really, really start to play with Vista.
