University District - Henry Gallery

The one I liked best in this cool sanctuary which was delightful even though there was barely any exhibits to see - but for - 

37,000 balloons in an installation of Martin Creed in a huge space that you could walk into and be utterly surrounded - I went in about three feet and came right out as it was HOT as well as claustrophobic and I went there to be cool!  The Extra shows just a tiny tiny portion of them.
