The use of time period-accurate materials to make contemporary contraptions ("Stonepunk doesn't exist" you might be saying "It's too far fetched!" Well, go to your dance search engine and look for "The Flintstones")
Old Greek/Roman style and ingenuity combined with post-modernism
(Can be its own Punk) Renascence era, or 'The Age of Enlightenment' aesthetic with modern contraptions (I like to think of Ella Enchanted with the crank escalator and such)
Post-modernism combined with the Japanese Edo period. It could also be called that if something like steampunk were combined with traditional Japanese aesthetic
A healthy combination of Victorian ingenuity and aesthetic combined with some contemporary/futurism technology and concepts
(It can also be its own Punk) A combination of the oil age and contemporary/futurism
(Can be a subset of Diesel) Focuses on the 20's-50's Art Deco design (I know one person who would love this)
1940s-60s modernism, which includes the Atomic age and the Space Age (could also be considered Raygun Gothic)
Contemporary Punkness... Not really too much to explain.
Extreme futurism normally associated with dystopia (The Matrix is a great example of Cyberpunk)
Focuses on the underground bio-technical revolution. This is different from Cyperpunk because it focuses on biology, not technology
A combination of post-modernism and mythology and folklore.
The use of any of the above Punk styles and combine it with Fairytales and storybooks (I have this kid an idea to write a story about a time-traveling Red Riding Hood and it was ecstatic about it)
