# Pi In The Sky, Literally

Ishky, a California-born artists collaborated with programmers and scientists to do one of the most compelling stunts: to write the first 1000 digits of the irrational number pi (or $\pi$) in the sky. Yes, literally.

The stunt was done in San Francisco Bay Area using five planes  at 10,000 feet.  The five synchronized planes wrote the digits of $\pi$ using some  dot matrix technology. The stunt was part of the Zero1 Biennial celebration.
