Ziegfeld Theater, Midtown Manhattan.
At a showing of Chicago the moviegoers, perhaps confused by the proximity to Broadway and the opulence of the theater, spontaneously applauded after all the song-and-dance numbers.

Lots of aviation geeks have been checking out the TWA Terminal photos lately. From this discussion I learned that the relevant authorities are still arguing over what to do with the shuttered building, and that it's featured in Catch Me If You Can (nice retro Flash, by the way).

Also, a reader in Athens writes:

Looking at the pictures triggered waves of nostalgia since the terminal was my very first "point of contact" with the US many, many years ago, when I first arrived as a student from Greece to your beautiful shores... In subsequent years, I often passed through the terminal, coming and going... One time, I spent the entire night lying on a bench in that central sitting bay overlooking the tarmac as a storm raged outside. ... I truly hope they find a way of preserving it. I bet many other people have feelings similar to mine regarding the building...

Jason recently posted about a geographically accurate map of the London Underground. The distortions of New York's subway map have no doubt had a big impact on people's mental maps of the city, their perception of how far away things are, perhaps even how much they pay for real estate. I always think my neighborhood is somewhat southeast of Manhattan, when in fact I'm really just south.

Speaking of mental geography, these maps are big in Australia.
