* the main display will be connected to a projector that will be projecting to a building that is 15 x 10 meters, distance between building and users is approx 20 meters.

* approx five clients (phones) will be connected at given time, each will have a aiming "cross" that will be projected onto the building and respond to their aiming (movement of the phone relative to the building)

* when user hits "fire" on the phone the typed message should appear on the screen instead of aim

it does not necessarily have to be android phone, if you have better idea - great!

Please bid only if you are serious developer and post a brief explanation of how would you do it and provide brief hardware specifications.
