Google has always created beautiful holiday logos. Some Google fans created a series of logos that can be seen on Flickr.
You can find more about Google doodles from their Holiday Logos museum.
Dennis Hwang's creative logos have been expressing the playful heart of Google behind the impressive technology.
For Piet Mondrian's birthday, Hwang transformed the "Google" logo to emulate the artist's signature style of utilizing colorful blocks. Claude Monet's birthday saw the logo turned into a dreamy watercolor, complete with floating lily pads.
