Because I get bored very easily.
But mostly because Blogger has decided to finally be awesome and give us these options. There are many more so the look may change more frequently from now on, because of the above reason.
Unfortunately, none of the pictures/patterns have anything remotely to do with cricket. There is a picture of a baseball that I contemplated putting, but then I realized I can't mislead you all. Wouldn't have worked anyway.
This is what I have been doing so I don't have to watch Deccan lose.
