Architect Frank Gehry is designing Facebook's new HQ, and they talked him into a side project: designing a playhouse to be auctioned off for charity.

"Architect Frank Gehry is the mastermind behind Facebook's new office space and world-renowned buildings such as the Walt Disney Concert Hall in downtown Los Angeles and the Guggenheim Museum Bilbao in Spain. Now Gehry has teamed up again with the social network, but this time on an unexpected project -- a ballet-inspired children's playhouse for a nonprofit's fundraiser." -- Queenie Wong, the San Jose Mercury News
