In need of a new screensaver? How about this nice Polar Clock by Pixel Breaker? It shows the date and time in growing color coded circles. Although it's not particularly effective at saving your screen (because it has a fair amount of non-moving or very slow moving graphics), it is fun to watch. Available in 2 versions (I kind of like the first better) for Mac or PC. If you don't want to install this as a screensaver you can also just experience it online here.
