The document discusses Jim Henson's approach to prototyping, which involved heavy use of sketching, storyboarding, and building minimum viable prototypes. It notes that Henson would sketch from a young age to explore ideas cheaply, used storyboards to plan projects shot-by-shot, and iteratively evolved his prototypes, hacking things together to see what worked. The document suggests taking inspiration from Henson's continual evolution and prototyping approach to making things up as a new industry.
