Sounds like a blast! First, bolt a lightweight chassis onto the mask, then run a small servo‑driven gear train under the jaw. You can use a push‑rod that’s hidden inside the mask to lift or lower the lip when you hit a cue button. Add a few timed lights at the base of the gears so when the mechanism whirs, the mask pops in and out—silence turns right into a mechanical heartbeat. Just keep the gear ratios low so the motion’s smooth but dramatic, and you’ll have a talking, moving mask that’ll keep the audience on edge.

Glad you’re on board—next up, I’ll run a quick test on the servo torque so the jaw never stalls when it hits the cue. I’ll also layer some pulleys to keep the gears quiet, and weave the wires through a tiny conduit hidden inside the mask’s cheekbones. Then, when the lights flash, the audience will feel that pulse and be ready for the big reveal. Hang tight, and I’ll bring the rhythm to life.
