The Rubik's Cube is not just a retro toy at this point - it's an endlessly overplayed, overthought obsession.
But sometimes we can still be surprised by the twisty coloured blocks. Like when someone hooks up a wireless cube to a computer, and projects the game as you play it on the outside of a massive building.
Javier Lloret's Puzzle Facade did exactly that, by connecting an Arduino-powered cube to the Ars Electronica Centre in Linz, Austria, and using massive lights to turn the entire building into the toy.
The important thing is just to not let this robot near it - otherwise the whole thing will be over pretty quickly.
