When the 3x3x3 or 4x4x4 are too tough, Try the 2x2
A few months back I got my self a 4x4x4 Rubiks Cube and after a few hours I managed to complete.... 1 layer. The next 3 layers are next to impossible in my book on a rubiks cube that size. Along comes the 2x2 which has a lot less combinations and should be in reach of the average lower then genius person such as me.
Anyway, this particular entry is not about rubiks cubes alone. The 2x2 is now built in to a keychain to attach to your mobile phone in Japan. I guess it will sit along side the flashy lights which flash each time your phone rings or has any kind of activity with a near by cellular tower. The 2x2 minicube will cost about $2.50 although I have no clue if they will come to England and Im not too fussed if they dont
