I just ran across another site that's got some art doing Star Wars, Steam-style. These are illustrations done by a guy named Eric Poulton. Looks like there's some neat stuff on the blog as a whole, but what really caught my eye was the Death Star.
I'd love to see a really good direct-to-DVD animated movie to come out that's in the Steampunk genre. Maybe the only way to get that would be something like an "alternate Star Wars universe" series. Preferably put together by someone other than Lucas.
