Spanish artist/designer Javier Lloret has created what is possibly the nerdiest (and coolest, in our books) interactive façade ever. Puzzle Façade, a 3D-printed interface cube that's connected to a digital wall by Bluetooth, lets passersby try their hand at solving a larger-than-life Rubik's Cube.

The tools and pieces behind the interface cube

The handheld cube is made up of 3D-printed exterior pieces (the twistable cubes we've all grown to love and hate) and a digital core that connected wirelessly to a laptop that controls the projection on the façade. As the challenger twists and turns the physical cube, the LED lights transform accordingly. The actual cube is a pristine white, making it harder for those who have memorized their puzzle-breaking pattern. Check out the video to see it in action:

The Ars Electronica building in Linz, Austria is the perfect canvas for this project. The LED-lit media façade was a ready candidate for the interactive display Lloret was looking to achieve with his thesis project. The catch: Due to the architecture of the building, the player is only able to see two sides of the cube as they work through the puzzle—making it almost impossible to match all of the colors. The player is able to flip the cube and feature different sides of the puzzle on the digital wall.

The best (and potentially worst) part of this installation? No matter how terrible you may be with a Rubik's Cube, no one will really notice your confused twists and turns with all of the lights flashing on the wall. On the flip side, depending on how well the installation is promoted, you could look like a total novice if people know what you're doing. Either way, better to brush up on your puzzle-solving skills before you take this one on.
