A projector, a balcony, and Super Nintendo emulator.
The best use of a giant screen was a guy that setup a projector at night for his kids on the opposite building, and a showdown of Street Fighter 2.
Chun Li and E. Honda ducking it out in a 200 ft. screen looked epic.
The audio, fortunately, didn´t match the size and distance of the "screen" and could not be heard on the footage.
