I just found three more items with a Buy in Brooklyn connection on my Google News page -- and no, I didn't do a search for them.
The Brooklyn Paper has a story today about the Snowflake Celebration. (The article also references the Umbrella Experiment briefly.)
And speaking of the Umbrella Experiment, The New York Times has a pair of stories about them. One, dated November 30th, gives a good chunk of background. The second, dated December 2nd, is more of a progress report.
