Mom and I walked by the sea serpent at the Google campus in South Lake Union. It’s called “The Wanderer”, a large-scale rainbow-hued sculpture that appears to have slithered out of Lake Union and paused amid the office buildings, like some Loch Ness monster that suddenly decided it likes the limelight. The triple-arced snake shape is intended to break up the rectilinear cityscape. is one continuous taper — starting at 30 inches in diameter at the head and diminishing toward 0 by the tip of the tail. The team painted the steel segments in gradient color (transitioning from blue to green to yellow) in order to give it a slinky sense of movement. It includes an animated light element running snout to tail that will be “visible at night and on dreary winter days,” Culler says.
