There are two main kinds of steampunk. The first, which shall be called here, traditional steampunk, envisions a future as the Victorians imagined it. The writings of H.G. Wells and Jules Verne are good examples. The second, industrial steampunk, sees a far future world that harkens back to Victorian culture, for example a bustle dress made of kevlar. There are also other temporal options like clockpunk (c. 1500s) and dieselpunk (WWII).
I just love the whole idea and the amazing design used, the goggles shown here are great, but I thinks its really cool having a complete costume, very MadMax.
