At the Hirshhorn Museum and Sculpture Garden in Washington DC we encountered an exhibit called, "Suprasensorial."
It was spectacular.
Our favorite pieces from the exhibit were Carlos Cruz-Diez's
Jesus Rafael Soto’s
“Blue Penetrable BBL”
We waited there for a spell watching Oliver play among the blue nylon forest of hanging string. He would have been happy to stay all day.
As you can probably imagine, besides the room full of mobiles by Alexander Calder, the rest of the museum's exhibits of sculptures and painting were sort of a let down for a couple of people who know very little about art, and a little bit offensive for people that don't like to look at nakeds.
