12 years ago, I covered the launch of artist Jason Polan's project to sketch every single person in New York City (he'd previously sketched every work of art in the MOMA). Now, via Kottke, I've learned that Polan has died at 37, from colon cancer. Like Kottke, I corresponded fitfully with Polan after I wrote about his work, and he was a delightful correspondent.
