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 kernel, which drives the animation. Quartz Composer brings all the technologies together and renders the final synchronized output using Quartz Composer Visualizer.
