If you're a fan of the Need for Speed series of racing games then get a load of the NFS Pro Street Race Clock screensaver.
This animated image works on newer S60 devices with Flash Lite installed, and will show up in older devices as a static wallpaper. But, to be honest, it doesn't make a lot of difference, because the animation is so basic it was hardly worth the designer's effort. All that happens is that a few of the lights around the speedometer flash in different colors, and the Pro Street logo at the bottom changes color. It would've been nice if the speed dial changed, or if the car span around or something.
As it is, NFS Pro Street Race Clock screensaver is pretty dull and will only really appeal to hardcore Need for Speed players.
