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.

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. :)

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.
