What
- Engineered a film prop for a ninja-themed production: a foldable, multi-part throwing star with a mechanical linkage.
- Developed a circular base with two pivoting blades that deploy or retract to suit the choreography.
How
- Used pin joints and screw-fastened pivots for smooth, realistic movement when handled.
- Shaped the blades with crescent cut-outs and a central aperture for an industrial look that holds up in close-up shots.
Results
- Delivered a working prop with real movement for actors and stunt performers, reducing the need for digital effects in post-production.
- Produced a manufacturable design with precise assembly tolerances for reliable, repeated use on set.
