A sea of silver ripples is making waves in Pershing Square in downtown Los Angeles, California.

Liquid Shard, a kinetic sculpture by Poetic Kinetics, created a canopy of silver streamers while blowing in the wind on Saturday.

The installation, with its latticework of holographic mylar strips and monofilament, stretches about 1,400 sq m across the park and rises, falls and slithers with the wind, the Los Angeles Times reported.

Designed and built by artist Patrick Shearn, the installation has become an instant hit, mesmerising downtown residents, office workers and tourists alike while spawning thousands of posts on social media, the report said.

Mr Shearn and his team used 3D computer modelling to assess how the structure would hang and move in the space, it added.

They then attached thousands of metallic strips to a grid of high-tech fiber rope and bungee cords, the LA Times report said.

The exhibit, which will be on display until Thursday, is part of efforts by the city of Los Angeles to support public art displays, it added.
