Appfall is an interactive screensaver just like the app wall at WWDC. It includes two mini games that can be played using app icons as giant pixels.
Appfall downloads app icons from the App Store top 400 charts for any region, category, or chart type, and drops them from the top of the screen laid out in a colorful rainbow. It can be set to display either Mac apps or iPhone or iPad apps.
It can also be set to display the more popular apps more often, can be set up to run as a screensaver, and supports multiple screens.
Appfall is also a great way to find new apps. Point at any icon to see the app's name, then click to see more information and a link to the App Store.
In the blocks mini game, the goal is to get as high a score as possible by clearing lines. Clearing more lines at once gives a higher score bonus. Use the arrow keys to move, rotate, or drop the blocks.
