Steampunk concept will blow your mind
Steampunk is a sub-genre of science fiction, alternate history, and speculative fiction that came into prominence during the 1980s and early 1990s. Steampunk is often associated with cyberpunk.
They have considerable influence on each other and share a similar fan base, but steampunk developed as a separate movement. Apart from time period and level of technology, the main difference is that steampunk settings tend to be less dystopian.
