What is Steampunk?
What is Steampunk?

"A subgenre of fantasy set in an era or world where steam power is still widely used—usually the 19th century, and often set in Victorian era England—but with elements of either science fiction or fantasy, such as fictional technological inventions like those found in the works of H. G. Wells and Jules Verne, or real technological developments like the computer occurring at an earlier date. Other examples of steampunk contain alternate history-style presentations of "the path not taken" of such technology as dirigibles or analog computers." (Wikipedia)
