bring back the mosaic screensaver to MacBooks and AppleTV!
There use to be a mosaic screen saver in my old macbook pro that would display one photo from your library and would zoom out to reveal more photos in a mosaic that as it zoomed out further would become yet another picture in your database. This was the coolest screensaver ever... come on Apple, bring it back!
MacBook Pro, OS X Mountain Lion (10.8.3)
