The Rubik’s Cube was the one toy that, along with Lego, launched the careers and piqued the interest of techie-minded kids around the planet when it was released back in 1980. Since then it’s sold in the hundreds of millions and become an instantly recognisable icon of maths-as-plaything. And now, thanks to Stuart Gorman, it’s a chandelier!
Instead of coloured stickers on movable pieces of plastic, Stuart’s version uses programmable LEDs which are animated according to the rules of the original toy (controlled by an Arduino Mega). It’s absolutely mesmerising to watch, and the incredible thing is that it solves itself.
