Anyone who admires the work of Scottish sculptor Andy Goldsworthy should see this amazing film. Goldsworthy uses found materials in their natural setting, and documents the natural processes which change and eventually destroy them. The film showcases Goldsworthy's astonishing patience, and also his spontaneity, in a way that his own photographs and writing can't convey. A highlight for me was watching one of his leaf-chains being swept down a stream, snaking and swirling along with the current.
Another remarkable film from the same director is Touch the Sound, about deaf percussionist Evelyn Glennie. The film isn't just about her, it's also about sound itself, and how conscious she has become to the nuances and possibilities she senses all around her, without hearing as we do.
