'Yayoi Kusama: Infinity Mirrors" is now open at the Hirshhorn Museum and Sculpture Garden. This much-anticipated exhibition, complete with dazzling lights, mirrors, polka dots and pumpkins is bringing in large crowds. "Infinity Mirrors" will be open through May 14. The Hirshhorn is releasing advance free tickets every Monday at noon for the following week on their website -- but if you want them, you'll have to act fast; they've been getting snapped up quickly. A limited number of tickets will be available daily at the door.
