Bill Thompson at Barbara Krakow.

Sculptor Bill Thompson's wall-mounted works probe the seductive possibilities of shape, finish and color. Each of his small, intensely fussed-over sculptures-formed of polyurethane panels with polished surfaces of acrylic urethane, are elegant but with an edge of self-reflexive irony. One suspects that Thompson is playing on the idea of the artwork as fetish. This latest show held at the Barbara Krakow gallery in Boston, Massachusetts, displayed some new geometric tricks and more delectable, candy-colored paint jobs in his wall sculptures, which can be rectilinear or free-form, low or high relief. A few works on paper were also on view.
