Does anyone here remember the exhibit at the Brooklyn Museum of a 20th
   century painter who was widely admired for his experimentation with
   materials, and even admired because of the transience of the
   materials he used? [forgotten the name, of course, it was in the early
   90's that Brooklyn did this show] We went to this exhibition with an
   artist friend who was really taken with the work, most of which had
   blackened and peeled to a kind of brown mess.  It stuck in my head,
   not for the aesthetic pleasure, but because I had never before
   encountered the idea that artists would intentionally work with
   transient materials.
