German artist Wolfgang Laib will create his biggest pile of art yet in MoMA’s atrium — a bright yellow 18 by 21 feet field of hazenut pollen that he collected from a southern German village next to his studio for over 12 years. So, the pollen, nut and birch sensitive might want to get their MoMA trolling in now before January 2013, when the aromatic Wolfgang Laib: Pollen From Hazelnut will take over the museum. The very allergic: Beware the pollen chamber!
