The other day when I logged into Gmail, I was greeted with the ability to add a theme to the look of my lovely gmail. Apparently this hasn't been rolled out for everybody, but I am one of the lucky ones. Wooohooo!
They give you several choices, and I, of course, chose the ninja theme.
(Does anyone know what that says?)
I suspect most people have chosen the ninja theme. Why? Because ninjas kick ass, that's why. I'm sure by now if you've spent some time on the internet, you know the three main facts about ninjas:

2. Ninjas fight all the time
3. The purpose of the ninja is to flip out and kill people
Anyway, the cool thing about the ninja gmail theme (and I'm assuming the other themes as well, but I don't know for sure) is that it's constantly changing. There's a little image at the bottom of the emails that's different every day. Here's what I've seen so far:
