I often use visual studio 2005 side-by-side with visual studio 2008. Do you remember the visual studio 2005 power-toy event toaster? You could configure it to pop a balloon in the system tray when a build was complete.
Is there a FREE plug-in for visual studio 2008 that does the same thing ? I really miss the event toaster. I used to zone out during long builds and the friendly POP sound it made when the build was complete would wake me up.
