After been amazed at someone solving the cube in 2 minutes blind folded when I attended a friend's wedding a while ago, I recently decided to pick up Rubik's Cube. After two days of practices, now I can successfully solve it in about 10 minutes. Still a long way to go...and a lot more to learn. It is definitely fun.
Some interesting facts I found:
- It is invented in 1976 (before I was born!)
- It is said to be the world's best selling toy (but guess what, I cannot find it in Target or Toys R Us)
- The world record for solving a standard cube is 9.7 seconds
- Beyond the 3x3x3 cube, there are names for 4x4x4 (Rubik's Revenge) and 5x5x5 (Rubik's Professor's Cube)
- Someone patented a method to create cubes up to 11x11x11
- There are 4 dimensional cubes and 5 dimensional cubes, and only a handful people reportedly have solved them
- Despite having more than 43,252,003,274,489,856,000 permutations, a cube can be solved in <26 moves.
A little math would show that only a tiny tiny percentage of those permutations have ever existed on Earth.

How did you solve it? I got it down to the last move (i.e. colors in the right corner) but never figured out how to rotate those colors. But everything before I solved myself.
