The Serpentine Gallery Pavilion appeared to be a complex random pattern that proved, upon careful examination, to derive from an algorithm of a cube that expanded as it rotated. The numerous triangles and trapezoids formed by this system of intersecting lines were either transparent or translucent, giving a sense of infinitely repeated motion. The outside surface was smooth and flush while on the inside the depth of the steel ribs was set by their structural load, adding a 3-dimensional layer to the internal space. The filtering effect of this 'hyper' skin created interesting patterns of light on the floor. By day the pavilion was a café, by night a venue for lectures, discussions, parties and films. It was also carefully built to the structural standards of a permanent building so that it could be taken down and rebuilt somewhere else. The pavillion was erected and dismantled in 2002.
