Sunrise, Sunset (Revolution) originally consisted of nine triptychs of graduated heights that appear to rise and fall like abstract mountains, and correspond to the Sun’s path from east to west horizons. Three thousand prisms, installed both by the artists and by local students and community members, were held within the aluminum panels. Wide arms beckon with sparkling red, orange, yellow, blue, green and violet lights, drawing visitors near. People are playfully surprised to find clear glass activated only by natural light. Prisms create countless rainbows on visitors’ feet and other surfaces. The prisms’ curved compositions follow the Golden Ratio, again linking natural science and art. The title offers a parenthetical, perhaps humorous reminder that Earth is spinning on an axis and traveling around the Sun, enormous but generally overlooked facts. Reflecting the artists’ intention that art and beauty is for everyone, the site-specific work was assembled with public participation. After its temporary exhibition at Pier A plaza, two segments of the piece were donated to BPCA’s permanent collection and installed on the northeast and northwest corners of Nelson A. Rockefeller Park in 2019.
