‘The big experiment in the sky’ Atop Salesforce Tower, one of the world’s highest works of public art comes to light wit

Sam Whiting, San Francisco Chronicle, May 20, 2018

Electronic artist Jim Campbell sat in Blooms Saloon on Potrero Hill, looking out the window and across town at Salesforce Tower. As day turned to dusk, he pressed a button on his laptop and the top 130 feet of the tower came ablaze in yellow LED light. Then the dark figure of a ballerina came dancing across the yellow light 61 stories up, and one of the world's highest works of public art was alive for the first time.
