We were searching the web for women sculptors and learned of Lee Bontecou. Her works were one of the inspirations for Red Vortex. After we finished the rebar circles and their connections, we saw the work of Eric Gushee. We got the steel wire connectors from his work and the rusted steel panels from Lee Bontecou. We considered a number of finishes for the rebar. Red enamel paint covered with Penatrol for durability was the final choice. The panels are rusted steel roofing also coated with Penatrol to preserve the rusty patina. It is designed to be hung rather than supported by a base, because bases are really difficult to integrate into a sculpture. This gives it the additional dimension of motion. It was made as a 95th birthday gift for my mother, Donna Livengood. Happy Birthday. Hope your birds enjoy this. It is 32” x 32” x 18”.
