One of this weekend’s cheaper alternatives to the Armory Show, Spring/Break, let artists loose on the cavernous, underutilized spaces of an historic post office in Chelsea. Think of Spring/Break as PS1 to the Armory’s Met, or something. Exciting work was straggled throughout the western side of the building, where there were surprises, and surprisingly few yawns, at the top of every balustraded marble staircase and behind each shadowy doorway. What reigned at this fair was humor, pop culture, technology, and an outsider-ish dedication to transforming banal materials or even crafty processes into wows. See our favorite moments, in no particular order, below.
