Frieze London is an art event showcasing some of today’s most talented contemporary artists and is happening right now. One exhibition which caught my eye was a kind of rubix cube installation by Berlin-based Angela Bulloch. A sculpture of flashing ‘pixel boxes’ lights in the Mayfair showroom of Rolls-Royce was a one-off piece for Bulloch, inspired by, she says, the technology and quality of leatherwork and veneers that go into the making of all their cars.
