Steampunk is a sub-genre of science fiction, alternate history, and speculative fiction that came into prominence during the 1980s and early 1990s. Specifically, steampunk involves an era or world where steam power is still widely used—usually the 19th century and often Victorian era Britain—that incorporates prominent elements of either science fiction or fantasy. Works of steampunk often feature anachronistic technology or futuristic innovations as Victorians may have envisioned them; in other words, based on a Victorian perspective on fashion, culture, architectural style, art, etc. This technology may include such fictional machines as those found in the works of H. G. Wells and Jules Verne or real technologies like the computer but developed earlier in an alternate history.
A few years ago the steampunk craze took over Nerf and some amazing paint jobs was the result of that. Some guns are still functional and others are all about the art and loose functionality. I love some of the mods but I have to say I'm glad people have moved on because I was getting tired of seeing Nerf guns with copper tubes just glued on and being called art. Here are a few examples of some of the better mods.
I may have to try a steampunk mod myself.
