Wow. Wow, wow. That's all I could think of during my time at MoMA's PS1 MOVE! event today. Cecilia Dean, she of Visionaireand perfectly-pulled-back-hair fame, co-organized the fashion/art extravaganza, which ran from 12-6 PM today and continues tomorrow. Collaborations included Terence Koh and Italo Zucchelli (of Calvin Klein), Brody Condon and Rodarte, Cheryl and American Apparel and more. Each room in the space featured different performances and happenings designed by the teams—and the energy pulsating throughout the building was palpable. I felt like I was back at (a much cooler version of) NYU art school.

Lancôme-sponsored makeup artist Alice Lane led a small army of intrepid face painters in creating each of the pairings' looks. This included, most notably, coating Koh's performers in head-to-toe “silver leaf'. “We made them shave everywhere, and then we set thin sheets of aluminum foil with Vaseline,” Lane explained. “It's peeling off, but that's the point—they're supposed to feel like atomic robot people,”

The Cheryl room offered full “makeovers', with glitter flying, music pounding, paint dripping and hair everywhere. It was sort of like if MAC, Betsey Johnson, American Apparel and Patricia Field opened a pop-up store. “One of my assistants was being way too detailed and careful,” recalls Lane, “so I literally stuck my hands in the paint, pressed them on the face and threw glitter on top. You almost need to have little kids do it—a makeup artist thinks about it too much. We need a troop of 10-year-olds,”

The grown-ups in attendance—including Stefano Tonchi and James Kaliardos—seemed to be enjoying themselves. Jim Shi test drove Lancôme's yet-to-be-released tangerine nail polish, custom blended for L'Wren Scott's Spring 2011 show. And I took a spin through Marc Jacobs's interactive installation: a runway, complete with faux flashbulbs, leading to a screening room with a projection of yourself catwalking.

I'm not sure that any Halloween activity could be better, but of course, there's always the Inez and Vinoodh-hosted Visionaire party tonight.
