Pi in the Sky
As part of an art installation for the 2012 Zero1 Biennial in the San Francisco Bar Area this week, five planes equipped with dot-matrix skywriting equipment -- like the Geico Skitters we wrote about in May -- took to the air. They flew in a 100-mile loop writing out the first 1,000 numbers in pi, the result of a collaboration between California artist ISHKY and Zero1. Local photographer Chiara took this lovely image of the partial sequence.
