Space Invaders 2006 is an outdoor video game, developed by Evan Barba and Kuan Huang, that takes advantage of real world architecture spaces and transforms them into a game playground. Basically, the video game is projected onto a building. The player controls an aircraft by moving his/her body in the space to shoot down the invaders before they move off the building.

The invaders come out of the wall cracks and move down to the ground. The player has to move left or right to control the motion of the aircraft. Whenever the player jumps, the aircraft shoots out a bullet.
