Today is the 71st birthday of the first showing of the movie, The Wizard of Oz. To celebrate the day, Google has a special doodle, aka logo, up for the significant date. The Doodle barely makes out the name Google, but it is clearly a representation of the movie.
Here is a picture of the Doodle:
I should note, there is some confusion for those who have set their custom background on Google.com. You will see “doodle balls” spinning, which signifies a Google Doodle is available on the main Google home page. To see it, all you need to do is click on the doodle balls. I have more information about how that works at the Search Engine Roundtable.
