cyberpunk, can revolve around a single type of technology like prosthetics, such as in Ghost in the Shell (GitS). Often named examples of postcyberpunk novels are Neal Stephenson's The Diamond Age and Bruce Sterling's Holy Fire. In television, Person has called Ghost in the Shell: Stand Alone Complex "the most interesting, sustained postcyberpunk media work in existence." In 2007, San Francisco writers James Patrick Kelly and John Kessel published Rewired: The Post-Cyberpunk Anthology. Cyber noir Cyber noir is a noir genre story placed in a cyberpunk setting. Retrofuturistic derivatives As a wider variety of writers began to work with cyberpunk concepts, new subgenres of science fiction emerged, playing off the cyberpunk label, and focusing on technology and its social effects in different ways. Many derivatives of cyberpunk are retro-futuristic: they reimagine the past either through futuristic visions of historical eras (especially from the first and second industrial revolution technological-eras), or through depictions of more recent extrapolations or exaggerations of the actual technology from those eras. Steampunk Steampunk is a retro-futuristic genre that is influenced by the Steam Age, ranging from the late Regency era (1795–1837; when the Industrial Revolution began) through the Victorian era (1837–1901) and the Belle Époque (1871–1914). The word steampunk was invented in 1987 as a jocular reference to some of the novels of Tim Powers, James P. Blaylock, and K. W. Jeter. When Gibson and Sterling entered the subgenre with their 1990 collaborative novel The Difference Engine, the term was being used earnestly as well. Alan Moore and Kevin O'Neill's 1999 The League of Extraordinary Gentlemen historical fantasy comic book series (and the subsequent 2003 film adaptation) popularized the steampunk genre and helped propel it into mainstream fiction. The most immediate form of steampunk subculture is the community of fans surrounding the genre. Others move beyond this, attempting to adopt a "steampunk" aesthetic through fashion, home decor and even music. This movement may also be (perhaps more accurately) described as "Neo-Victorianism", which is the amalgamation of Victorian aesthetic principles with modern sensibilities and technologies. This characteristic is particularly evident in steampunk fashion which tends to synthesize punk, goth and rivet styles as filtered through the Victorian era. As an object style, however, steampunk adopts more distinct characteristics with various craftspersons modding modern-day devices into a pseudo-Victorian mechanical "steampunk" style. The goal of such redesigns is to employ appropriate materials (such as polished brass, iron, and wood)
