1. iPhone TV Wall

When you have a party or camping, maybe you what to make a large display temporarily. iPhone could be one solution. Collect some iPhones or iPod Touchs from attendee, and Wifi or 3G network is needed. Setup one iPhone as server, others as client. Setup each client, choose the it’s position in the “TV Wall”. Then send controlling UDP packages from the server, each updates it’s screen. One obviouse weak point is that the “TV Wall” maybe is too expansive. :)

There are many hardware implementations of POV, such as Arduino POV.

POV Sample

Maybe iPhone could be used to implement one: install a iPhone on a wheel, and make a physical pulse each round for start point signal. Maybe iPhone’s brightness and screen refreshing rate is the key problem.
