Skywriters Spelled Pi to 1,000 Places in San Francisco Sky

The sky over the San Francisco Bay Area has been used as a screen by a team of skywriters who managed to spell out the value of Pi to 1,000 places.

It would be interesting to note that to organize the "Pi In The Sky" skywriting event the team needed five planes that flew in sync in a loop over 100 miles long.

The piece was made by Stamen Design, artist also known as Ishky, for the 2012 Zero1 Biennial.

Unfortunately the geeky artwork was temporary; in fact by the time the team had created the 1,000th digit, the 3.14 has already disappeared.
