I remember someone mentioned this before. Winamp has a feature called AVS. Nothing more than effects that change with the music. The interesting thing about it I like is the ability to send the image to the desktop background. It uses the Video overlay option of the video card. When I discovered this I keep Winamp running all the time now
It would be a great feature to have the Aquarium running the same way, on the desktop background as wallpaper, right there behind everything, icons and all, full size. TOO COOL
