Simon and Vya - A True Scientific Mind

NOT MY JOKE! I totally stole it from this xkcd.com/242/ (which is incidentally the first xkcd comic I ever saw, way back when I was a wee freshman in high school, one of the guys in the class before me had drawn it on the whiteboard in math class)

Anyway, since I couldn't be original, I decided to make it pretty instead and do lots of nice shading.

Hopefully I'll post something better next time
