When British painter Howard Hodgkin, winner of the Turner Prize in 1986, first confronted the Quantel Paintbox, he found his own working methods were accelerated to an almost alarming degree. In his own studio, Hodgkin works, sometimes for years, on his own brilliantly-colourful, almost abstract, canvasses. Now, with the computerised brush and palette of the Paintbox, Hodgkin can achieve a 'painted' sketch in a matter of minutes. He responded to the challenge by using the computer to work out ideas for the sets and costumes for Stravinsky's ballet Pulcinella - a commission from the Ballet Rambert.
