Now off to google what Steampunk actually means....

Steampunk is basically making anything contemporary look like it came out of a Victorian clockmaker's shop

It's all about old world clothes and steam technology aesthetics and cogs combined with current ideas and mechanics. A really great example is this steampunk lego competition:

Or another really way to think of it: anything in the movie "Wild Wild West" (with Will Smith) could be considerd steampunk, albeit sort of watered down.
