But the fact that on September 12 this year, 1000 giant decimal places of pi appear in the sky over San Francisco and the surrounding area, in any textbook was said. However it happened, and the result is very impressive — look.

This event started the artist known as ISHKY, together with the firm Stamen Design, and the entire project was called Pi in the Sky.
