The Academy tribute to the groundbreaking effects of Jurassic Park made me recall that Phil Tippett had previously shared some of his early work for the film before the dinosaur animation switched over to computer-generated imagery. This video is one of several pre-vis animations done with stop-motion puppets to plan out the design of Jurassic Park's most iconic sequences. And while this rough stop-motion animation isn't as fluid as the eventual scene (which combined CG with Stan Winston's life-size puppets), there's a distinct sense of craftsmanship that you get from watching stop-motion--you can appreciate how an animator adjusted the raptors' movements and body language in every frame. Tippett also uploaded the stop-motion test for the T-Rex Jeep Attack sequence here.
