Pop! Kick! Zou! Inspired by legendary pinball machines, 21 Obstacles is an architectural video projection that turns a building’s facade into a giant video game.

The game is activated by passersby and the adjoining 21 Swings installation on the Promenade des Artistes. The movement of the swings directs the actions of the obstacles, each swing controlling the behavior of a different obstacle.

Passersby join the game with their cell phone, by texting an indicated keyword to launch a ball into the melee, drawing variable trajectories, and when user’s balls interact with an obstacle, visual effects are triggered, creating fantastical and imaginary journeys.
