Any Steampunk themed media is welcome! Although Deadwood is more in the line of the classic western, the
victorian style that was popular in the U.S. during that time, as well as the machinery that was being produced on through the early industrial age, would fall into the Steampunk genra. Such as steam powered vehicles and generators for the prodution of electricity, and such.
Anything that you can dream up, even that which reaches into the far future such as space travel, looked at from the possibility of those achivievments being made without the science related to the modern, advanced technological revolution, or nuclear age would be great.
For example: in the Wells novel
"The first men on the moon", The achievment of space travel was concieved, and acomplished, by the gear, and valve mechanics of the ship, and the chemistry of the Anti-gravity element
"Cavorite".
Even if you want to do some victorian styled furniture, or buildings, that would be useful as well. I would say that the best example of
"American Steampunk" would have to be that of the film
"The Wild, Wild, West".
