"Pi In The Sky The world’s largest ephemeral installation is scheduled to appear in the sky above the San Francisco between Sept. 12 and 16. It will display 1000 digits of Pi a 1/4 mile high each." Merging art and technology, ISHKY has brought together a team of artists, programmers and scientists to give life to a compelling vision that a community of millions will directly experience. The conceptual work, Pi In The Sky, explores the boundaries of scale, public space, impermanence, and the relationship between Earth and the physical universe. Your generosity will set this momentous and historic undertaking in motion. (...) Pi In The Sky has two unique interpretations, one within Earth's atmosphere and one well beyond it: At 10,000 feet altitude working with our technical partner AirSign, a team of five synchronized aircraft equipped with dot-matrix technology will skywrite the first 1,000 numbers of pi's infinite sequence in a 100-plus-mile loop around the San Francisco Bay Area. Each number will measure over a quarter-mile in height." http://www.kickstarter.com/project... - Amira
