The last time I was in London, I visited the old Tate, anticipating what I thought would be a room full of Constable paintings. Looking forward to some illuminating picture-viewing I followed the gallery map to the appropriate room and found instead scaffolding, dropsheets, paint cans, and other materials scattered about. At first a little disappointed, I did however find this an interesting subject that might make a painting, so I took some photographs. It looked a lot to me like a contemporary art installation.
