Now, this is pretty cool. At the World Wide Developer's Conference (WWDC) in San Francisco this week, Apple put together a live wall featuring 20,000 of the most popular iphone applications, sorted by color. When an app was downloaded off their site, it would animate in real time (or on a delay of real time) as a ripple effect across the screen. Quite an impressive little exhibit display for sure. The intention was to reinforce WWDC attendees that 3,000 apps are downloaded every minute - and to encourage developers to engage with this format. More information can be found at AppleInsider, where I pulled the following photos. Video via YouTube.
