Artwork in the form of canvases or framed posters is a great idea, alternatively there are some lovely Steampunk wall clocks available. You can find Steampunk designs on throw pillows or you can get some gorgeous ornaments that have a Steampunk flavor to them.

This Steampunk inspired gas mask would certainly make an interesting piece to have on display in your home.
I certainly like it although I know my husband would prefer one of those old fashioned diving helmets, I'm not sure exactly where I'd get one of those however - they would be fantastic and would embrace my love of Steampunk elements and his love of diving!
There are lots of other things you can add such as a Steampunk weapon of some description or even one of the ornaments I've found for you below.
I particularly like the idea of a couple of Steampunk inspired boxes, however. This is because there's always something little that you need to keep somewhere so there's a practical use as well as just looking nice!
