The Exploratorium's Pi in the Sky.
March 14th is Pi Day. (Think about it.) And as part of the Exploratorium's celebration, they want you to enter into the world of ISHKY and join the "Pi In The Sky" effort. Merging art and technology, ISHKY has brought together a team of artists, designers and scientists to create a compelling vision for millions of viewers to share.
When activated, the conceptual work, "Pi In The Sky" will claim to be the "largest ephemeral art piece ever created."
