Query: Kanner Architects and Retro Futurism

Los Angeles has been the lucky recipient of a new wave of architecture generally referred to as Retro Futurism -- a modern, playful and elegant take on what one might call sort of a Jetsons sensibility. Kanner Architects practically invented this form, as one can see so wonderfully rendered in tbis book. This is a must for anyone interested in cutting edge buildings and modern architectural trends.
