A screenshot of the tyrannosaurus rex scene taking shape during the production of Jurassic Park, using an early version of SOFTIMAGE 3D that was made by the Montreal-based company, Softimage (later acquired by Autodesk).
At the time, the software was still "half-baked" according to fellow Canadian, Steve Williams, who pioneered the success of CG filmmaking at ILM, but its implementation of inverse kinematics was instrumental in bringing the film's dinosaurs to life.
You can find the screenshot—alongside a literal handful of other goodies—in the book, 'Jurassic Park: The Ultimate Visual History' by James Mottram:
