Ms Paint

I've seen some amazing drawings being produced with Photoshop, illustrator and painter, but what this guy produced beats 'em all. He spent 500 (five hundred, not a typo) hours on making a drawing with Ms Paint. If you don't know the difference between the previous programs and Ms Paint, then let me tell you it's like racing a Ferrari against a bicycle.
You can always try to make an even better image, but be clear to take a week vacation first ;).
