Using Bluetooth technology and the existing LED facade of Austria’s Ars Electronica Center, Spanish artist and designer Javier Lloret turned the building into an interactive 3D puzzle called “Puzzle Facade.” The colorful result is entirely reminiscent of a Rubik’s Cube.

io9 explains how the system works:

The interface for the massive puzzle is a 3D printed cube that closely resembles a real Rubik’s Cube, except that its pieces aren’t colored. The interface-cube contains electronic components to keep track of orientation and rotation. Data is sent via bluetooth to a computer that runs the Puzzle Facade software, which changes the lights and color on the building’s wall.

So unlike the Rubik’s Cube itself, Puzzle Facade players aren’t able to cheat by peeling off colored stickers and rearranging them on the outside of the building.

Check out the video to see how the interface works and enjoy watching frustrated onlookers struggle to solve the giant jumble.
