This article pretty much covers a great deal of my understanding of steampunk. As La Ferle says:
Devotees of the culture read Jules Verne and H. G. Wells, as well as more recent speculative fiction by William Gibson, James P. Blaylock and Paul Di Filippo, the author of “The Steampunk Trilogy,” the historical science fiction novellas that lent the culture its name. They watch films like “The City of Lost Children” (with costumes designed by Jean Paul Gaultier), “The League of Extraordinary Gentlemen” and “Brazil,” Terry Gilliam’s dystopian fantasy satirizing the modern industrial age; and they listen to melodeons and Gypsy strings mixed with industrial goth.
They build lumbering contraptions like the steampunk treehouse, a rusted-out 40-foot sculpture assembled last year at the Burning Man festival in Nevada and unveiled last month at the Coachella music festival in Southern California. They trawl eBay for saw-tooth cogs and watch parts to dress up their Macs and headsets, then show off their inventions to kindred spirits on the Web.
The focus on the fashions is especially interesting to me, as someone who likes to experiment with clothing or just dream up what characters in 19th century settings may possibly wear:
And, in keeping with the make-it-yourself ethos of punk, they assemble their own fashions, an adventurous pastiche of neo-Victorian, Edwardian and military style accented with sometimes crudely mechanized accouterments like brass goggles and wings made from pulleys, harnesses and clockwork pendants, to say nothing of the odd ray gun dangling at the hip. Steampunk style is corseted, built on a scaffolding of bustles, crinolines and parasols and high-arced sleeves not unlike those favored by the movement’s designer idols: Nicolas Ghesquiere of Balenciaga, Alexander McQueen and, yes, even Ralph Lauren.Steampunk is growing. Wonder if I should invest in more than just a corset.
