Lighting artist Leo Villareal put forth his “Point Cloud” installation inside new pedestrian bridge over Howard Street. The bridge connects Moscone Center convention halls on both sides of the Street, and only conventioneers will be able to walk the span and see “Point Cloud” up close. There are 67 circuit breakers to power 67 rows of lights. Each row is made of a series of stainless steel rods, 858 of them suspended from the roof of the bridge. On each rod are LED bulbs facing east and west, for a total of 28,288 each bulb is individually programmed.
