At Apple’s Worldwide Developers Conference (WWDC) in San Francisco, an App wall has been installed in the lobby of the Moscone Center, featuring one icon for each of the existing iPhone Apps, and whenever someone somewhere purchases an App for an iPhone, its icon pulsates on the wall. The result is an undulating wall reminiscent of a roiling sea. The number of Apps on the wall is astonishing; apparently, it’s no hyperbole when the voiceover in the iPhone commercial says, “There’s an App for that.” (via Towleroad)
