We first came across the work of Janet Cardiff a few years back, when her immersive, multi-sensory walking tour "Her Long Black Hair" graced Central Park in the summer of 2004. For those who missed it, it was a truly transforming piece of work, in which the "viewer" is given a CD player that acts as guide, commentary and soundtrack, constructed from 3D sound recordings so realistic that real and recorded sound blur together, creating a hyper-aware dreamlike state in which questions of loss, longing, history and observation are addressed in a wholly unique way.

It's only recently we discovered that Ms. Cardiff also creates installations, and a recent one, entitled simply "Killing Machine," has got to be one of the creepiest contraptions we've seen all year. A room-sized construction including weirdly anthropomorphic moving tools and loudspeakers, and an articulating fur-covered dentist's chair, the Machine uses sound, light and motion cues to evoke a real sense of dread, and embody "an ironic approach to killing and torture machines." The five minute Quicktime movie is worth watching, especially at the end, when the lights come on and we're reminded that it's just a bunch of stuff.
