In 1974 Errno Rubik invented the “Magic Cube” which is widely know as the Rubik’s Cube. We all know about it since I believe everyone has it. To prove my point it is know as the best selling toy of all times with over 300 Million sold worldwide.
Rubik’s Cube cultivated such a following that there are contests around the world and this year a guy called Erik Akkersdijk solved in 7.08 seconds! That is a world record by the way and here is the video.[kml_flashembed movie="http://www.youtube.com/v/VzGjbjUPVUo" width="425" height="350" wmode="transparent" /]
So everyone understand the cube has 43,252,003,274,489,856,000 possible positions. Yeah, that is a LARGE number BUT it can be solved in 25 or fewer moves since there is an algorithm to do so.
Over time, the cube has evolved and there has been a lot of new ones, like a 4x4x4 cube and a 5x5x5 one. The latest one though and very cool is called “Mirror Rubik’s Cube” and it is made out of mirrors.
It works in similar way, but each face has a block of different shape, so when you start moving it around it loses the “cube” form. Here is a video of the unboxing of it.
