In November of 2013, Belgian artist and designer Kris Temmerman installed an 8-bit arcade game titled Invasion on his house window, inviting pedestrians to play for free. Temmerman developed a game in which "the world gets invaded by aliens and you have to fight your way to the end boss, save the world and the human race" with Arduino. Previous efforts by the Antwerp-based artist include an Arduino Painting Machine and a series of Hairy Kinect Pictures. Brilliant.
