The App Wall at Moscone Center was impressive. The Appstream app, based on that concept, is cool, too. It turns out, the App Wall can work as a screensaver for Mac as well.

The developers over at iapp.pl created a very simple screensaver that simulates the App Wall already seen at the WWDC. I don’t know whether this constantly pulls data from iTunes or not, but no doubt it is cool. And it’s available for free here.
