Drawing a perfect circle

The Kircher Society has a fabulous post about people drawing perfect circles freehand, with artistic and literary references. I prefer not to have this blog just be a link tracker but that post in its entirety is just, the penultimate example of what an informative blog post should be so I thought it merited a link. The society's site also seems exotic and interesting, like a blend of Damn Interesting and Three Weeks. (via)
