Sculpture: Spare Parts #7 by Paul Martia

A tall steel blade, with little cities of brass cubes clinging to it at odd heights.

Spare Parts #7 is a contemporary sculpture by Paul Martia, in steel, brass and copper. Sculptors working in welded metal have long made art from industrial offcuts, and the technique rewards the roughness of the material. A narrow vertical blade of steel with a wavy edge rises from a flat metal base. Two thin horizontal bars cross it at different heights, and clusters of small square blocks in golden brass gather along them. Fine ridges mark the edges of the bars, and a thinner plate stands off to one side. It is 9.75 inches wide, 2.75 deep and 21 high.

Spare parts, and no spare ideas.
