I read about Gwyneth Leech's installation in the Prow gallery at the skinny end of the Flatiron building, "Hypergraphia, paper cup drawings", and was able to see it just before it came down as we had planned a short trip to NY. She's collected and decorated paper cups for years and there are over 800 suspended in the space. Such a simple idea but they looked jewel-like behind the glass.
