Do you like trigonometry?
The Greek mathematicians always struck me as very classy-looking people. Maybe it was the togas, maybe the beards, maybe the distant, thoughtful stares. Anyway, their respective images in sculpture always seemed aesthetically pleasing in my math books.
That being said, you did a nice job translating what was probably a stone piece into an image with personality. I would have liked to see a little more below the neck, just so that he's not a floating head, but it's otherwise decent.
The floating theta, pi and other math miscellany are nice touches, but they're not incredibly involved in the piece, and they seem kind of haphazardly included, as if they were an afterthought. I'd like to see him consumed by the symbols, see them swarm his head with a blank look in his eyes, as if all the secrets of mathematics were exposed in that instant.
I'm a sucker for educational humor, though this just barely qualified. I guess it makes me feel kind of elite to immediately recognize a theta as it pertains to math. Oh well, it works in your favor!
