It’s all well and good when the MacArthur “Genuis” Grants go to musicians, mathematicians, and authors. But I also love the outliers, like paper historian Timothy Barrett or stone carver Nicholas Benson. I hope 2012’s grantee class includes Kilian Martin, who is re-imagining what can be done with a humble skateboard. After watching this short video I thought of Michael Jackson’s dance moves, Tauba Auerbach’s typographic painting, and Merce Cunningham’s choreography. Whatever the difference between performance art, modern dance, gymnastics, and the athleticism of skateboarding, Kilian Martin is right on top of it.
