Until Tarot just resurfaced in my life a little over a year ago, I had never heard the term 'Steampunk'. None of my non-tarot friends have heard of it either. Maybe it's because we live in the sticks.
I just don't get the whole concept....
Steampunk came from a sub genre of fantasy fiction and science fiction. It's been a hugely popular genre for about ten years. Check out the early novels of China Meiville.
The concept (in a nutshell; I'm not an expert) is that the internal combustion engine was never invented, so modern devices are all based on the steam engine. Even spaceships will run on steam. It often has a Victorian England flavor because of the steam technology.
