According to an article from http://blastr.com/2009/09/guide-to-sci-fi-punks.php there are 11 most popular punk cultures
The ones interest me the most are:
Particularly because I've seen movies that uses those frequently.
For example like:
Steampunk = Golden Compass, League of Extraordinary Gentlemen, Howl's Moving Castle
Cyberpunk = Matrix, Blade Runner, Neuromancer
Dieselpunk = Watchmen, Dark City, Hellboy
Mythpunk = Pan's Labyrinth, Narnia, Skeleton Key
It's easy to visualise the scenes because they have their own style of settings. Steampunk would be art nouveau like design and architecture, Cyberpunk will have many modern technologies, Dieselpunk would have art deco buildings and noir feel, and Mythpunk is very dreamlike. I found each one of them very fascinating.
