Picture of the Day: LEDs enable Rubiks Cube building

Puzzle Facade 2013 - Javier LloretThis one is amazing. Puzzle Facade (2013) is a project by Javier Lloret, which “brings the experience of solving a Rubik’s cube to the urban space”…

It’s a very novel use of Bluetooth comms, LEDs, and a Rubik’s cube interface. It transforms the Ars Electronica’s facade – in the city of Linz in Austria – into a giant Rubik’s cube. Twist and turn the little cube in your hand and watch the chunks of colour move and turn across the building….

Electronic components of the 3D-printed, handheld Interface-Cube include:

  • Arduino:
  • Bluetooth modem
  • Orientation sensors
  • Rotary encoders
  • LiPo battery

Interface cubeJavier Lloret writes:

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.

Puzzle Facade was part of Lloret’s thesis of the Interface Culture master program at the Universität für Künstlerische und Industrielle Gestaltung Linz, Austria.
