Unexplained Phenomenon

The Google US homepage and other local Google homepages are currently showing a UFO logo doodle (the flying saucer shown seems to kidnap the a letter from the logo). In the US, the search query linked from the logo is "unexplained phenomenon".

On September 5th, 2009, Google tweeted out “1.12.12 25.15.21.18 15 1.18.5 2.5.12.15.14.7 20.15 21.19”, a cipher for “all your ’O’ are belong to us”. The cipher was based on a straight alpha-numeric transliteration, wherein 1=a, 2=b, 3=c, etc., Google coincided this tweet with a www.google.com homepage graphic in which a UFO is abducting the second ’O’ in Google.
