When dinos met digital doom
The Oral History of the Dinosaur Input Device (DID)
Before CGI took over, a wired dinosaur puppet nearly saved old-school movie magic
TLDR: Jurassic Park nearly used stop-motion dinosaurs, but a clever hybrid tool called the Dinosaur Input Device helped old-school animators survive the switch to computer-made creatures. Readers are obsessed with the irony: a fake dinosaur puppet became the bridge between classic movie craft and the digital age.
The big gasp from readers wasn’t just "wow, Jurassic Park almost looked totally different"—it was the emotional whiplash of watching old-school effects artists stare down extinction in real time. The article retells how Phil Tippett’s team expected to bring the dinosaurs to life with stop-motion puppets, only for a secret computer-generated test to blow the doors off and send the movie in a new direction. Commenters were instantly divided into two camps: the "CGI changed cinema forever" crowd and the "practical effects had soul" nostalgics, with plenty of people saying this story felt less like movie trivia and more like a workplace apocalypse with dinosaurs.
The star of the drama is the wonderfully named Dinosaur Input Device, basically a sensor-covered dinosaur puppet that let traditional animators move a physical model while the motion got translated onto a digital creature. Community reactions ranged from awe to comedy. One popular vibe was, "this is the most 1990s solution imaginable"—instead of surrendering to computers, they strapped the old craft directly onto the new one. Others called it a beautiful survival story: artists refusing to get wiped out by a tech shift. And yes, the jokes were everywhere. People compared the DID to a “steampunk joystick,” a “prehistoric game controller,” and the “missing link” between handmade movie magic and the digital future. The mood across the thread was half reverence, half meme storm, with many readers saying the story captures the exact moment Hollywood learned the future was coming whether anyone liked it or not.
Key Points
- •*Jurassic Park*’s full-motion dinosaurs were originally intended to be created as stop-motion puppets by Tippett Studio before ILM’s CGI tests changed the plan.
- •Tippett Studio and ILM developed the Dinosaur Input Device to let stop-motion animators drive CG dinosaur animation with a physical, sensor-covered armature.
- •The DID later received an Academy Technical Achievement Award, with Craig Hayes, Brian Knep, Rick Sayre and Tom Williams named as recipients.
- •The article includes firsthand accounts from Phil Tippett, Brian Knep and Craig Hayes about go-motion, stop-motion planning and the transition to digital methods.
- •Before the CGI decision was finalized, ILM experimented with using MORF-based interpolation to add synthetic motion blur between stop-motion frames, though the process was slow.
