For his thesis project in “Interface Culture” at the University of Arts and Industrial Design Linz, designer Javier Lloret converted the entire facade of the Ars Electronica building in Linz, Austria into an interactive Rubik’s Cube called Puzzle Facade. Lloret created a handheld device the mimics the function of the ubiquitous puzzle toy which then wirelessly communicates with a computer that controls the network of lights installed on the building. From his website:
In Puzzle Facade the player interacts with the specially designed interface-cube. The interface-cube holds electronic components inside that allow for it keep track of its orientation and the rotations of each side of the cube. This data is sent over Bluetooth to a computer that runs the Puzzle Facade designed software. This software changes the lights and color of the large-scale Ars Electronica’s media facade in correlation to the handheld interface-cube.
Due to the nature of this building and its surroundings, the player is only able to see two sides at the same time. This factor increases the difficulty of solving the puzzle, but as the player is able to rotate and flip the interface-cube, it is not a blocking factor.
