Might as well show mine as others have shown theirs. Ahem.
The first one is a a larger version of my avatar. I was just bored and reading Neuromancer at the time (as if that is an excuse). Slightly dodgy photoshopping.

This other one was taken a couple of years ago by a photographer friend. I call it my too-early-in-the-morning-to-be-in-a-graveyard look. Spooooooky. Or tragic.

Also, note that I now have one of those annoying images as my sig. A fun five minutes in photoshop with that one.
Toodle pipski.
