I assure you that it was an extraordinary –an overwhelming- experience to be present at this spectacle. When I came away I was intoxicated, moving in a world of fantasy. I didn’t go to bed until nine in the morning after prowling around all over the town, on land and on water, and watching a variety of spectacular sunrises. Why was this performance so good? Because of something to which I want to draw your attention. There are certain exactly proportioned spaces of perfect harmony which one could describe as places of ‘visual acoustics’ –places of such perfect proportions that the onlooker is made one with the surroundings.
