Just a quick link to some absolutely brilliant fan art of China Miéville’s The Scar:
City of Armada by Benjamin Sjöberg (thumbnail on left is a close-up of a portion of it)
The rest of his blog has some excellent sf/f art, including a few pieces based on Chasm City by Alastair Reynolds.
EDIT: Oh damn, I just looked back through the blog and found a ton of other Scar-based work. It’s all viewable here!
