This style relates to the pre-digital period of 1945-1965, including mid-century Modernism, the Atomic Age and Space Age, Communism and concern about it exaggerated as paranoia in the USA along with Neo-Soviet styling, underground cinema, Google architecture, the Sputnik program, superhero fiction, the rise of the US military/industrial powers and the fall-out of Chernobyl.
Inspired by industrialized Western civilization during the 19th century. Set in an alternate history of the 19th century's British Victorian era or American "Wild West", in a post-apocalyptic future during which steam power has regained mainstream use, or in a fantasy world that similarly employs steam power. Features anachronistic technologies or retro-futuristic inventions as people in the 19th century might have envisioned them, and is likewise rooted in the era's perspective on fashion, culture, architectural style, and art. Such technology may include fictional machines like those found in the works of H. G. Wells and Jules Verne, or the modern authors Philip Pullman, Scott Westerfeld, and China Miéville.
A manipulation on an alternate version of a future 1950s from the developed technology and society of the 1930's, where the Great Depression never arrived and World War II is still being fought as a prolonged Cold War. In turn, Japan continues its progress towards technological modernization, developing the earliest computers and terminals. Nazi scientists continue experimenting by taking the route of biotechnology, sparking off a genetic revolution of bio-mods, clones, and organ harvesting. Whilst the Americans and British take both of these technologies to develop mind-control devices, spawning man-machine interfaces. Primarily focused on using devices with internal combustion engines.
The fashion presented in The Matrix is a primary example of this style. Examples being trench coats, sunglasses, boots, goggles, plus black, monochrome and occasionally neon materials. Popular hair styles can include woven dreadlocks, shaven heads, and unnaturally dyed hair colors (red, blue, green, etc.). This fashion resembles a combination of industrial, rave, punk and Gothic fashion. Some common themes include a contrast of black or white combined with luminous neon or UV-reactive colors and materials, brightly colored and often stylized hair, large shoes or boots, various forms of body modification, the presence of superfluous goggles (especially Aviator sunglasses), androgyny and the influence of anime themes.
This style is the same time period as "Victorian Era". One should start with something that appears in old gunslinger films and add once again futuristic elements to weapons or gadgets. That may sound complicated, but can involve something as simple as wiring on metal rocket looking attachments to the barrel of your six gun, attaching a miniature flashlight laser pointer to the top as a laser aiming sight, making the bullets glows with fiber optic lights, or plugging the barrel with something that looks like a raygun transmitter and wrapping copper wires and unidentifiable gizmos around the weapon. Don't forget gadgets, goggles, brass, corseting, compass, etc.
