Nearly a year to the day after signing up to co-host of Revision3 geek how-to show Systm, David Randolph has left the show to pursue a gig with an unnamed new client — that a tipster is guessing to be Pixar, based on a blurry phonecam picture of the studio's latest creation, Wall-E. It makes sense on two levels: One, Pixar is incredibly secretive. And two, having been behind the gates once myself, the place is littered with models of movie characters past and present. Hope this little peak behind the scenes doesn't get Randolph fired by an enraged Steve Jobs.
