Our eyes are set to graphic visualizations.

Mashable explains:

Here at WWDC in San Francisco, Apple has once again erected a video wall demonstrating the reach of the App Store. It contains 30 synchronized 24-inch LED screens that display the top 50,000 apps as they are being downloaded. In just a few minutes, the entire walls gets filled up with with 10,800 downloaded apps from around the world.

[…]
“This hyperwall is powered by 30 Mac Pro towers with Mac OS X Snow Leopard and EVGA NVIDIA GTX 285 graphics cards. As apps are downloaded from the App Store, their data is coalesced via an XML feed every five minutes. Apps are sorted and scheduled using Cocoa and Objective-C. The data is then passed to an OpenCL kernle, which drives the animation. Quartz Composer brings all the technologies together and renders the final synchonized output using Quartz Composer Visualizer.”
