That one is interesting. I was on the F train, and the V train was passing by on the local track. Somehow the reflection of it in the glass made that V just seem to float in the middle of my car (in the picture, of course; if that happened in RL I'd be bugged).

You can get some nice shots of downtown from the skywalk at night, though. I'm thinking some long exposures and some steady shots would be really good. Not that my camera is capable of either of those.
