Steam Punk. It is an aesthetic that I quite enjoy, with all that brass and Victorian retro-ness. An alternative view of the late Industrial Revolution, with its Meccano Engineering and delicate Art Nouveau design. Pistons, tubing and Steam power, bring it on!
The one thing that annoys me a bit is the 'cogs on everything' idea.
I like cogs, they are a brilliant way of transferring, changing and modifying motion, but I don't like cogs that have no purpose. A cog has to DO something, even if that something is a mystery to the on-looker. A cog whose sole purpose is to sit there and look steam punky is a cog with no direction in life. That is a sad state of affairs. If you look inside and old clock (not a digital one) you will find a lot of cogs and gears, some spinning fast, others barely moving, but they all work together for the one goal, to provide an accurate measurement of time; nothing is superfluous, and everything works by clockwork.
I mean, a top hat with goggles is pretty cool, but a hat with goggles and gears, that's just a bit weird. Unless those gears and cogs add to the functionality of the hat, even if it's in a fairly obscure way, they really shouldn't be there. Ah, but it's decoration you say. Well, why not use a stylised bronze Art Nouveau Ostrich feather? Save the cogs on your hat for opening a flap on the top to deploy a hidden harpoon gun or some scientific apparatus! Cogs are functional. They are made to do something, let them do it!
Anyway, when I think of steampunk, I picture a bloke with a pink Mohican having a steaming cup of English Breakfast Tea, probably with a scone...
