Conceptual sculpture

Work by Waldo Evan Jespersen, in his show "Stretched,'' at Boston Sculptor Gallery, Dec. 14-Jan. 28.

The gallery says: "Driven by formalism and problem solving, Jespersen's work represents the distillation of a thought pushed through the filters of reality and compromise. Often engineered to push the boundaries of materials and processes, as well as his own ability, Jespersen's sculptures are surprisingly elegant, whimsical, and deceptively simple in their purity of form. The process spurs an endless playful battle between the juxtaposition of a simple concept and complex construction.''
