Rubik's Cube 1980 to 2012

Invented in 1974 by Hungarian sculptor and professor of architecture Erno Rubik, it was originally called the 'Magic Cube'. In 1980 it was the biggest selling toy of the year here in the UK - and by January 2009, still as popular as ever, over 350million cubes had been sold in total, worldwide. Now that really is a popular toy! So... did you ever manage to solve it (without changing the stickers)?!
