The "puzzle piece" like shapes are meant to be the numbers 2-0-1-2 representing the year 2012.
There's nothing unusual about that, but what's the purpose of the "dot-like" block in the middle? It doesn't having anything to do with the numbers and it doesn't relate to anything about the games or London either.
Well, not only can these "puzzle piece" like shapes be looked upon as the numbers 2-0-1-2, but they can also be representitive of the letters Z-I-O-N.
That's pretty neat, wouldn't you say?
And guess what, it also makes use of that "dot-like" block in the middle of the logo that seems to serve no purpose otherwise. (It does dot the "I" in Zion pretty nicely after all, doesn't it?)
