I have no yen to go anywhere. But I go around the world anyway to see what's there -- and to see if I'm in the right place. Flying to Japan, the first thing I saw was a field of snow that you could walk on, then a sky paved with clouds ... wherever I go, I have an eye out for rocks. Outside my hotel in Phnom Penh I picked up a stone and carried it back around the world in my purse. Stones, bones, clouds -- experience gives me shapes -- but sometimes the shapes I paint end up having no resemblance to the actual experience.
