Paul Allison, Tech Liaison for the NYCWP has posted the results of their recent walking and writing tour of the Museum of Modern Art in NYC. Check out what they're writing -- and what they're seeing when they do. I like how they've taken the pictures and the text and put them together in Flickr. Their work might make for a good set of writing prompts for you if you're feeling stuck.
Really. Go look and read already.
