I have to agree with the other reviewers-- the Silver Clouds were my favorite part. This is the most uplifting and playful room that I've seen in a long time at any museum. I'm a sucker for installations, especially ones that I can interact with so completely...and because of the nature of Warhol's work and how much everyone has been exposed to it over the years it was so familiar...I just really loved it.
The rest of the museum was great too-- I loved lingering over the many prints and paintings that are so iconic and exciting, and seeing the countless snapshots of Warhol and his hangers on and their weird glam life. Interesting that you're allowed to take pics there, but conceptually appropriate...you'd get shown the door in Boston's art museums for that.
