Puzzle Facade brings the experience of solving a Rubik’s cube to the urban space. It transforms the Ars Electronica’s media facade, into a giant Rubik’s cube, inviting passers-by to engage with an interactive experience that takes place in the city of Linz (Austria).In Puzzle Facade the player interacts with the specially designed interface-cube. The interface-cube holds electronic components to keep track of rotation and orientation. 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.
