Apple Revamps WWDC Video Wall with Mac Pros, Cinema Displays

Apple’s traditional World Wide Developer Conference App Store app wall got a make over this year with 30 24-inch LED Cinema Displays driven by 30 Mac Pro towers. The video wall shows the activity of the 50,000 most popular apps at the App Store sorted by app icon color.

The wall represents App Store activity by dropping the icons for apps as they’re downloaded, creating an app icon waterfall effect. Apple is aggregating download data every five minutes via an XML feed and processed with code built with Cocoa and Objective-C. Final rendering for the video wall is handled with Quartz Composer Visualizer.

Apple’s video wall offers a striking visual representation of just how many iPhone, iPod touch and iPad apps are being downloaded, and just how often the most popular apps are purchased.

Apple’s World Wide Developer Conference runs from June 7 through June 11 at the Moscone Center in San Francisco.
