A building in Sao Paulo has been turned into a ridiculously enormous monitor for a game of Tetris.
The games were controlled using an iPad, and projected onto the sides of entire buildings.
The titles include a Tetris-like block stacking game, and a specially-created version of Space Invaders in which a bicyclist has to shoot cars, for some reason.
"It's weird and a lot of pressure, but it is really cool," said one of the gamers.
The aim was apparently to encourage residents to notice their surroundings, and pay homage to the retro art of the old, old school.
