The ephemeral event, known as Pi in the Sky, utilized five aircraft with dot-matrix skywriting technology to write out a thousand numbers of the beloved mathematical constant pi (3.14159..) at a 10,000-foot altitude. If that wasn’t impressive enough, the numerals of pi written in the sky each stood nearly a quarter-mile tall, stretched for a 100-mile loop, and undoubtedly caused mass inspiration and confusion all at once.
California artist Ishky collaborated with art and technology network Zero1 on the geeky endeavor, billed “as largest physical expression of pi ever created” and part of the 2012 Zero1 Biennial, a massive Bay Area event that celebrates the convergence of contemporary art and technology.
But of course anything in the sky is fodder for the chemtrail conspiracy theorists. A Google search for Pi in the Sky chemtrails finds some pretty amusing hits.
