Spanish artist and designer Javier Lloret has managed to convert Austria's Ars Electronica Center into a gigantic and functional Rubik's Cube. Called Puzzle Facade, it works by sending signals to a ready-built LED-lit wall using a 3D-printed interface-cube.
The six-floor building is located in Linz, Austria, and is often referred to as the "Museum of the Future." It already features an LED-lit media facade, making it a perfect canvas for the project.
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.
Museum-goers are encouraged to give it a shot — but only two sides of the building are lit, making the virtual Rubik's Cube considerably harder to solve. But players can flip the cube to feature different sides of the puzzle on the wall.
