Drawing a picture by rolling your mouse on Circles

 Thanks to StumbleUpon, I noticed this peculiar site today. I could not understand what it was in the beginning, but later it showed up its beauty. In the beginning, you will only see a big circle, but when you rollover on it, its splits up. It was fun, but then I realized there was even more fun hidden in it. In fact, on rolling over, you reveal a hidden picture. It makes the whole thing lot more interesting. I looked upon it source code to see even better things! You could hide your own image within the circles.
 To customize the circles here is what you have to do.
Easy right? Now find who is hidden in the following Circle!
