Tobsen has a few nice pulpy pieces.
One of these to race around in - Tobsen's Seagull, my paintjob:

Or perhaps one of these to lurk under the oily water - Tobsen's Globo, my paint again:

(or indeed on a dockside or in a mad inventor's harbourside warehouse, which is why I built the pallet/stand for it!)
There's been some very, very nice harbour scenery projects on LAF, about to shut the computer down for the night here but search for "harbour" (and "harbor" to catch the folks who can't spell properly). Grimm's Lovecraftian harbour comes to mind; there's been a couple of others too.
