San Francisco-area geeks may have thought they were dreaming last week when they looked up at the sky and saw… Pi (3.14159265385…). Five skywriting planes took to the skies above the Bay Area on Sptember 11 to create the world’s largest ephemeral art installation —  the first 1,000 digits of the infinite sequence of pi. The hour-long, 150-mile flight, naturally named “Pi in the Sky” was dreamed up by San Francisco artist ISHKY with the support of Pizone, a group that uses pi to educate and engage students and the public to become more interested in math and science.
