Engineering firm Skidmore Owings and Merril collaborated with American artist Phillip K Smith III to create Santa Monica Linear, a mirrored glass installation that lights up at night.
Santa Monica Linear sits on a sloping landscaped site on the grounds of a house designed by celebrated Californian modernist Ray Kappe.
Santa Monica Linear is 30 feet long
Made of steel and glass, the 30-foot-long (nine metres) artwork is a horizontal slash that reflects the sky and trees.
At night, LEDs turn it into a shifting light display that echoes the famous sunset of the beachfront California town.

Architect-turned-artist Phillip K Smith III worked with SOM's director of structural engineering Eric Long to design the site-specific piece and install it on a steep-sided hill.
"The simplicity of Smith's concept and beauty of the site posed direct challenges to the perfect implementation of the artwork," said SOM.
"Of particular importance was the 42-degree sloped site and the necessity of the 30-foot-long mirrored plane to be a perfectly level extruded form, free from internal structural elements."

During the day, the mirrored surface reflects the light and scenery. As night falls, the LED display shows a shifting array of light and colour like an artificial sky.
