By far the best exhibit outside of Spain that I have seen on Salvador Dalí is on right now at the MoMA. Dalí: Painting and Film shows a rare glimpse into the surrealists full body of work including rare films like Un Chien andalou (The Andolousian Dog) which was absolutely stunning. It was VERY surreal to watch because Jason and I were just talking about it a few days ago and didn't know this exhibit was on.
Catch this exhibit if you can. Entry is $20/day and on until 09.15.2008 at MoMA.
