Humans like patterns.
Some people like to extract extra meaning into coincidental patterns.
I think it's of note that today is the 12th day of the 11th month of 2013. But I don't think it means anything.
Especially since people in other parts of the world note the day first and then the month, which would make today 12/11/13.
And in cultures that use the lunar calendar it's totally different. In each of those cultures it's totally different.
So enjoy the accidental pattern, but I don't think it means much more than a nice shadow on the wall.
