Steampunk Recs
A couple friends of mine are going to be opening a store this summer that has a steampunk aesthetic. The location they're going to be in is fairly heavy on the foot traffic (which they're counting on) and we're looking for ideas for books and/or movies that you might use to illustrate basic steampunk for people who've never heard of it before so that they have things to point to and go 'like this!' on hand when people ask.

Basically, anything that instantly comes to mind when you think 'steampunk'. We're casting our net wide here, so anything you can come up with would be awesome! Thanks!

Edit: Thank you for all the suggestions so far! Also, I've gotten full permission to plug the store in the wilds of the internet, so here is the Otherworlds Store Site.
