Rotation

After so much of learning, rather so little ...... we moved ahead and learnt some new 3D stuff, which looks awesome. When I first saw this type of an Animation I thought its something equivalent to bending a "metal rod" but when i learnt making it and finally made it ......... I now have no words to explain how simple it is, may be to me it is as I am graphic student but might not reach someone else's IQ :).
Please don't get too impressed.......
