[00:19.73]Modern sculpture rarely surprises us any more. [00:23.91]The idea that modern art can only be seen in museums is mistaken. [00:30.26]Even people who take no interest in art cannot have failed to notice examples of modern sculpture on display in public places. [00:39.93]Strange forms stand in gardens, and outside buildings and shops. [00:45.73]We have got quite used to them. [00:48.43]Some so-called 'modern' pieces have been on display for nearly eighty years. [00:54.61]In spite of this,some people -- including myself -- were surprised by a recent exhibition of modern sculpture. [01:03.62]The first thing I saw when I entered the art gallery was a notice which said: The objects on display were pieces of moving sculpture. [01:13.76]The objects on display were pieces of moving sculpture. [01:17.58]Oddly shaped forms that are suspended from the ceiling and move in response to a gust of wind are quite familiar to everybody. [01:26.37]These objects, however, were different. [01:29.92]Lined up against the wall, there were long thin wires attached to metal spheres. [01:36.06]The spheres had been magnetized and attracted or repelled each other all the time. [01:42.78]In the centre of the hall, [01:44.52]there were a number of tall structures which contained coloured lights. [01:49.35]These lights flickered continuously like traffic lights which have gone mad. [01:54.58]Sparks were emitted from small black boxes and red lamps flashed on and off angrily. [02:01.55]It was rather like an exhibition of prehistoric electronic equipment. [02:07.10]These peculiar forms not only seemed designed to shock people emotionally, but to give them electric shocks as well!
