Pontus Hulten

Tinguely wasn't the first artist to work with machines. But others were more interested in precision, in what machines are meant to do. What made him different was the random element. He introduced the mechanical accident. He was always interested in the immaterial, in sound, smoke, speed, light, shadows.

The '50s in general are written off as a boring decade following the turmoil of the Second World War and its immediate aftermath - the postwar Labour government, the cold war, the arrival of the New Look in fashion, etc. But I remember it as a very exciting time - a pioneering, rule-breaking time, especially for the young.

What I look for when I see a piece of art for the first time is some kind of emotional, intellectual experience, that's a combination of both of those things and is informed by my knowledge and something new that I see the artist doing.
