A rainbow of color sprung up across the Fort Point Channel this week as a new art installation took shape on the Congress Street Bridge.
Boston artists Michael Moss and Claudia Ravaschiere on Wednesday installed more than 1,700 light-refracting Plexiglas panels, painstakingly placing them inside each of the gaps along the bridge’s south-facing side.
The result when the sun hits them just right is a few hundred feet of Technicolor shadows.
“It really colors the sidewalk in a beautiful way,” Moss said.
The public art, which goes by the name “Shimmer,” will be there through late November.It’s a follow-up to another, smaller version of the artwork that was installed on one corner of the bridge in 2014.
The duo worked with a team of nine volunteers, who raced to bring the artwork to life in a single day, Moss said.
“It’s sort of more magical if it just shows up,” he said. “One day it wasn’t there, and then one day it was.”
