Mysterious Skywriting over San Francisco

Just a few minutes ago I looked outside to see a mysterious sight in the sky.  There was skywriting going on that was unlike any that I had seen before.  5 airplanes were flying at high altitude in perfect formation - wing to wing.  They would occasionally send out poofs of smoke.  The result was printing in the sky something like a dot matrix printer would make.  They were spewing out a long list of numbers.  It didn't look like a phone number, but rather a really long line of digits that must have been some sort of code.

Does anyone have any idea what this is?  It certainly is intriguing and I'd love to learn more about it.

Update:  This was an art exhibit called Pi in the Sky that was part of 2012 Zero1 Biennial.  They were spelling out the digits of Pi!  Pretty cool!  Apparently it was a Kickstarter project.  Read all about Pi in the Sky here.
