The Puzzle Facade project transformed a building in Linz, Austria into a giant, solvable Rubik’s cube:
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.
In other large-scale gaming news, designers recently honored Philly Tech Week by repurposing a building to host a massive game of Tetris:
The Tetris building was designed by Frank Lee of Drexel University and forms a sequel of sorts to the game of Pong, which he set up on the face of the same building last year and which, until this point, held the Guinness record for Largest Architectural Video Game Display. Tetris works by lighting up coloured LEDs that are attached to the shadow box spandrels on the building. But where Pong only made use of one side of the building, Tetris covers both the north and south faces.
