The Path - Abstract Geometric Form, Hand Painted Welded Steel Wall Sculpture
By Chris Hill
Located in Chicago, IL
This dynamic wall sculpture is created from sheets of steel, welded together in an abstract geometric pattern. Muted shades of blue, grey, purple and green dominate and are balanced by softer hues. While the work adheres to a rigid, rational geometry, this sculptures suggest lyrical movement, apparent weightlessness and improvisation as the title suggests.
