About two weeks ago, while we were in Washington, D.C., I went to the Phillips Collection to see the exhibition Snapshot: Painters and Photography, Bonnard to Vuillard.
It displays 200 personal photographs taken by 7 post-impressionist painters at the end of the 19th century, using the then-new Kodak handheld camera. Seventy paintings and prints are also shown. The pictures are engrossing, although many are only a few inches tall. It runs until May 6. See it if you can.
On the way down the stairs, I spotted this sculpture in the Hunter Courtyard.
It’s one part of a work called Sk(in). The other part was hung inside, but, unfortunately, it has been removed. The artist is A. Balasubramaniam, and you can watch an interesting short video on the full work’s installation here. The sculpture “explores the limits of perception.”
It certainly explores the potential of steel mesh.

I think I like the shadows more than the actual sculpture, which may be the intent.
I think so. In the video at the link, you can see how carefully the artist arranges the tilt of the big wire ball. (The part about the indoor installation is very interesting too.)
