Any eyes in San Francisco that weren't focused on Apple's announcements yesterday might have noticed something peculiar in the sky. As part of the ZERO1 Biennial -- a months-long festival celebrating the coming together of art and technology -- an artist known only as shky used several planes to skywrite the first 1000 digits of Pi over the city in a piece cleverly titled Pi in the Sky.
The stunt used five planes flying in formation equipped with synchronised dot-matrix-like smoke printers to slowly spell out the sequence. Each digit measured almost 800m in height, so anyone on the ground could easily distinguish the numbers, even though the planes were flying at almost 10,000 feet. A sixth craft was used to film the stunt from the air, but the wider view from the ground made the piece seem far mor grandiose.
But not everyone was impressed with Ishky's work. There are several videos on YouTube, including this clip, of Bay area residents who were left completely confused and somewhat concerned over a seemingly random sequence of numbers appearing in the sky. I hope you're happy, J.J. Abrams, because Lost has made us all paranoid of maths. [ZERO1 Biennial via Laughing Squid]
