Celebrate the 40th birthday of Rubik's Cube with today's Google Doodle

It must be hard being Ernő Rubik. Back in the 1980s, the architect and toy inventor had the rare good fortune of becoming one of very few self-made millionaires from communist Europe. But in the process he was horribly pigeon-holed. His patented Rubik's Cube sold 350 million units, while his other creations -- Rubik's Snake, Rubik's Magic, and presumably a few blocky buildings somewhere in Hungary -- barely got a mention. Today, you can contribute to the injustice of it all by celebrating the 40th anniversary of the first Cube prototype, courtesy of a playable Google Doodle. Meanwhile, the inventor is currently touring the world with an exhibition that is pointedly titled "Beyond Rubik's Cube." Ernő, you have our sympathies.
