Last night the force was with Washington Square Park as a Lightsaber Battle brought out the masses. But these weren't your father's lightsabers, Luke. 3,000 blacklight-reactive, meter-long cardboard tubes were distributed as massive blacklight cannons took aim, lighting up the crowd. After the battle was over, the tubes destroyed, and hopefully the intergalactic mess cleaned up... the crowd headed to a secret Brooklyn loft afterparty, which if these photos are any indication, was quite heavy on the dudes.
