You know that if a trend has hit a major office building, it’s really gone mainstream. The pixelated effect that has been seen in hip textiles and interior design is used for the glass facade on this SmithGroup project going up in Mission Bay. For people driving down Third St., it adds a bit of sparkle to the vista, reflecting the blueness of the open sky around it. Compared to the new Rafael Vinoly-designed UCSF cancer research building next to it (which Mitchell Schwarzer twitted for its blandness), it’s the sequined cocktail dress next to the Gap khakis.
