Rubik's Cube turns 40 today

I never did own a Rubik's Cube, you know, one of those colourful cubes where you twist and turn to get the colours to align. Just the other day, it occurred to me that I should own one of those just for nostalgia sake.

Today, Google commemorates the 40th anniversary of the Rubik's Cube with an interactive Google doodle. Yep, it's been 40 years!

Rubik's Cube is a 3-D combination puzzle invented in 1974 by Hungarian sculptor and professor of architecture Ernő Rubik. Originally called the Magic Cube, it won the German Game of the Year special award for Best Puzzle that year. As of January 2009, 350 million cubes had been sold worldwide making it the world's top-selling puzzle game. It is widely considered to be the world's best-selling toy.

Although the Rubik's Cube reached its height of mainstream popularity in the 1980s, it is still widely known and used. - Wikipedia
