Human Tetris, Pac-Man, and More

Artist Guillaume Reymond is a master of human stop-motion animation. For the project GAME OVER, he assembled large groups of volunteer "pixels" (read: people in colored shirts) in auditoriums, sat them in specific seats on the grid of seats, then carefully choreographed their movements to re-create classic video games. He makes the game's sound effects by making beeps and bloops into a mic. It's amazing, trust me.
Human Tetris
I'm impressed by two things here: first, there's a human "Next" box in the upper right; and second, the game speeds up as lines are cleared.
Human Pac-Man
Crazily ambitious, particularly the cutscenes.
Human Space Invaders
My favorite part: sound effects when the UFO appears.
Human Pole Position
Yep, they can even do a driving game.
Human Pong
This was the first attempt at the form. Pong is perhaps the least exciting game here, but the "meeps" make it work.
