A spinning Firefox logo. This is an aPNG example. As you know PNG images were lacking animation. But with Firefox 3 and aPNG you can know create animations with PNGs. Here a small but beautiful example. Watch out, it is not a GIF but PNG. Even it seems to have a black background actually it does not. Optimised for 1024x768 screen resolutions but it will look good on other resolutions, too. Drag it onto the middle of the screen if you need.
