Today google changed its logo to the one above. I must admit i did not get it at first. I inquired a little. It is inspired by the architect Frank Lloyd Wright. He created the NY Guggenheim museum building among others (the second G in Google logo)
You may ask why google chose this guy and why not another one? Well it is his birthday today (8 June)
When you click on google logo you reach all kinds of links related to him.
