Prototype This! TV Show in 2009

In a San Francisco Bay island warehouse, a crack team of engineers, PhD’s and a special effects wizard are inventing the future one prototype at a time. To solve the problems of today, the team imagines the craziest, one-of-a-kind prototypes of tomorrow, and then builds them. Join the PROTOTYPE THIS team on a journey through emerging technology as they invent the future.
