Calling all artists: making a roguelike game

Hello. I am looking for an artist to make tile-based graphics for my online roguelike game found at www.roguearcade.com. I am not in a position to pay, but the game would be a great portfolio piece for a young or freelance artist.

What I would require would be square tiles of all sorts, probably 100 - 200 including: environments, walls, doors, enemies, items, and GUI. Some art is already in place, so take a look. If you think you would be interested in this, please contact me.
