An artist is making an exhibition of pictures of him scratching the paint of cars with a key in Glasgow and London. “They should feel glad that they’ve been involved in the creative process. I pick the cars randomly. got the idea when my sister and brother-in-law’s cars were keyed. Is it jealousy that causes someone to key a car? Hatred? Revenge? There is a strong creative element in the keying of a car, it’s an emotive engagement.”
