On this furnace of a day, with strong hot winds and the scent of bush fires in the air, leaving my office air conditioning held little appeal. But I decided a short walk was worth it, to spend a little while enjoying the adult equivalent of playing under a backyard sprinkler. At the National Gallery in Canberra, not so far from my office, is a small but beautiful collection of sculptures. Below is Fog sculpture by Fujiko Nakaya (1976), which operates between 12.30 and 2pm – perfect for a cooling, slightly mystical lunchtime wander. And with such a strong, hot wind, both my camera and I were dry by the time I got back to the office.
