Metropolis - Initial Thoughts:
A city having reached a certain level of grandeur, not a town, not a city, not a village...
Black Rock city, I mean come on, a good number of people are already thinking that this theme effectively means Burning Man is the theme for Burning Man; Though we might want to save that for "Utopia" ;)
Comic books: This one sorta scares me. This will be my first burn, and I'm slightly afraid of seeing a lot of Batmen, and supermen roaming around or (temporarily) immortalized in plaster of Paris.
Tall Buildings, a city that has been well established and is reaching the pinnacle of its essence before its edges are partitioned off to become suburbs and smaller offshoots.
Communication, in any vision I've ever seen of a 'metropolis' has been one where everyone is connected easily to one another from financial tower to the lowliest hovel. In any 'metropolis' the separate parts must communicate to function.
Grand Architecture (no big step there) in the form of buildings that have gone beyond function to form, of statues that are beyond the individual and are only possible on a public scale.
Sadly I think of business suits, and schedules and drone like people scuttling about as part of the grand machine that holds up the roof. Most any congregation of people in the modern world that could be labeled with such a moniker is run at a backbreaking pace to keep up with supply and demand of its residence. Large cities seam to have a tipping point where they have to expand to survive, but can never again balance, so they keep expanding and eventually begin to fall to a central decay as their outlying edges are so far from the infrastructure that either the center or the circumference fails due to support.
Transportation, Mass (trains, planes, buses, boats, monorails) and personal (planes, cars, bicycles, helicopters, teleporters...)
OK running out of steam, I'm just trying to throw thought's into the communal soup :)
