A picture is worth a thousand words? Yes, but sometimes imaginatively mixing them results in a much larger multiplier!
Steampunk is a sub-genre of science fiction, fantasy, alternate history, and speculative fiction that came into prominence during the 1980s and early 1990s. Steampunk involves a setting where steam power is still widely used—usually Victorian era Britain or “Wild West”-era United States—that incorporates elements of either science fiction or fantasy. Works of steampunk often feature anachronistic technology, or futuristic innovations as Victorians might have envisioned them, based on a Victorian perspective on fashion, culture, architectural style, art, etc. This technology includes such fictional machines as those found in the works of H. G. Wells and Jules Verne, or the contemporary authors Philip Pullman, Scott Westerfeld and China Mieville.
Other examples of steampunk contain alternative history-style presentations of such technology as lighter-than-air airships, analog computers, or such digital mechanical computers as Charles Babbage and Ada Lovelace’s Analytical engine.
Various modern utilitarian objects have been modded by individual artisans into a pseudo-Victorian mechanical “steampunk” style, and a number of visual and musical artists have been described as steampunk.
