Way back in September I was able to steal a few hours in San Francisco to gawk about downtown. I was able to see the John Portman development (and his classic open-atrium hotel [see above]) and the new San Francisco Museum of Modern Art (it was only open for 50 more minutes when I got there; with a $25 admission, that was a 50-cents-a-minute whirlwind tour!).
The infamous sinking Millenium Tower. Just as the new millennium is sinking, so is the new Millennium Tower!
Liked how they used darker wood to mark the last step (and hovered the steps out from the wall on the sides).
The stairwells here are rather awesome.
