Three large-mesh nets, woven from blue artificial fibre rope, are slung wall to wall, one on top of the other, across almost the whole space of the Proposition Gallery. Supported in the top net are three large, brightly coloured, shimmering satin-covered objects: a blue cone, a red cube, a yellow sphere. In the middle net it is as if the same objects, deflated perhaps by escaping air, rest. Below, on the lowest of the levels, the three geometric forms have lost all their rigid lines, and in their softening their very substance is dripping through the mesh, collecting in shiny pools upon the wood floor. Thus David Barnes has taken the Platonic classification of form, and the primary classification of colour, for his installation. But in his effective piece, the forms refuse to remain in their original position in the index. Subject to external forces, they reject their pigeon-hole, just as artists do.

Runs until September 6th.
