So I'm sure you can see by the subject that I'm the lookout for some awesome steampunk story elements.

For those usure, steampunk is defined as:

"Steampunk is the science fiction of the steam age. Where conventional science fiction looks forward and asks "What will the future be like?" steampunk looks backward and asks "How might the Victorian Age have been different?...a fair amount of steampunk technology and the steampunk environment are historically accurate, or follow historical fact closely. Many of the incredible devices imagined by steampunk authors and enthusiasts were actually imagined, theorized, or even constructed by 19th and early 20th century thinkers."

I'm digging for things along the lines of time travel, medical science, metaphysics, machines and inventions, and anything else that would fit this subgenre. Basically, what would make a good steampunk story?
