#71To CH
first of all, "open" concept represented by opened top of roof, like opening a dish is my idea, i post it by #35 (but it still to stiff.). i saw someone used this concept (and he got a rank) :'( . i just combining my concept with another concept that make you interest, the meaning of bird hold an envelope is an open access to government information (represented by a free flying bird from the building holding an envelope).
hope you like it, please give it your feedback :)
