An installation at Paris’ Palais de Tokyo morphs and twists a grid of white structural beams into an impressive tangle of wood. Brazilian artist Henrique Oliveira designed the sculpture as a giant Gordian Knot (a legend referring to an intractable problem.) Oliveira created the branch forms from reclaimed tapumes – a Brazilian plywood material used around construction sites – twisting and bending it into shape, adding veneers for texture. The installation has the great effect of looking as though organic, chaotic nature took over the clean, minimal architectural space. On view through September 29.
