The form of the Broadway Triangle, by Mike Moore and his tres birds workshop, is fairly rational: a cluster of volumetric rectangles held in place by dark-painted girders overriding the outside. But then the craziness begins. The lower parts of the walls have been clad in salvaged bricks, with random ones having been painted in garish colors. Above that is a changing set of murals, with the first batch, organized by Melissa Belongea, having a street-art kind of flair and including individual works by Jolt, Jonathan Lamb & Michael Ortiz, the collective Palabros/Collabros, and Deepti Nair & Harikrishnan Panicker. Dada Art Bar, inside the building, is all arty, too, intending to present exhibits in addition to cocktails. The whole thing is set off on the 25th Street side by a cluster of lighted directional arrows on a spike, called "One Way," by Mike Mancarella. That piece has been there for years, but it feels like part of the project.
