That DT Rock Island one is brilliant.
Fire escapes can be made into the centrepiece of a facade. Here are a couple of great fire escapes, posted by Stepper77 and Haux on the 'My City' threads:

And of course, Richard Rogers has made an entire career out of bunging staircases onto the outside of buildings. I'm sure he got that idea from fire escapes when he was studying in the US.
Spiral fire escapes can look good too. They are popular in business parks in the UK:

More and more, I think that things like street signs, telegraph poles, wires, parked cars and fire escapes are as much a part of the urban fabric as buildings, and should be enjoyed. There's no point trying to turn cities into landscaped parks - and the messy, mundane things that people complain about the most often end up being the kind of things people get most nostalgic about when they're gone.
