Shake up your Windows 7 with Aero Shake
 

One feature of the Windows 7 user experience that wasnt demoed or even talked about last week at PDC 2008 is called "Aero Shake" - the same feature that led Rafael on an epic journey to unravel the secrets of build 6801 superbar. What Aero Shake does is allows you to shake your application windows furiously, to quickly minimize all other windows, at the same time experiencing a seizure in your hand. Its a pretty cool feature that I can see some practical use for it, but I think they need to work on the sensitivity so users don't wear out their desk.
