Swiss group &SÖHNE Film posted this really neat video of a custom multi-directional shooter projected onto a 10-meter-tall industrial building, offering some gaming entertainment at an early summer party.

It's more than just a game projected on a wall, though, as the shooter uses elements on the facade for its stage design -- the score and player lives are dispayed on a window, and players need to blast their way up columns to make it to the top of the building. 

&SÖHNE Film says it hopes to release the game online some time soon on its site, though I doubt it would be as fun as playing it with your friends outside and on a building wall during a warm evening. Maybe someone in the U.S. can make an event/party out of this?
