When Steven Spielberg brought home early footage of a stop-motion dinosaur from his new movie Jurassic Park, his kids' reaction couldn't have been more promising. They loved it. But Spielberg was unmoved; it wasn't quite right. That twinge of dissatisfaction, deep into pre-production stages, derailed months of painstaking planning. It also hatched a whole new species of visual effects, a breed that will be on display tenfold in Jurassic World. Though Spielberg's digital dinos were a first for the medium, designed on the fly in those heady pre-visualization days, they were so realistic, so present and expertly rendered, that watching them today is every bit as breathtaking as it was in 1993. Computing advancements have made CGI infinitely more doable, but those creatures looked quite right from the getgo, and still do.??
