Paris DP posted photos of his Walk/Don't Walk signage , so I thought I'd post mine.The red hand means stop. Recently they also added a countdown. It counts down from 10, but according to my calculations you have another 6 seconds before the light turns green.
The little white man means walk..and really fast too, because downtown traffic is so unpredictable. In the background you can see the Payroll Association building reflecting the library from it's bank of windows. You can also see the yellow/orange vehicle with advertising on it's side—I'm seeing this kind of stuff all over the place now.
