What is Steampunk?

Steampunk is a relatively new genre classification.  It's a little hard to explain.  Essentially, it takes place in the past, but it has technology similar to the present.  Although, instead of running on electricity, these things run on steam.  (Think about the movie Wild, Wild West with Selma Hayak.)

Here's a great, fun, youtube video that shares more about Steampunk.
