Sounds ambitious but doable if you break it into clear stages. First, hook up a reliable heart‑rate sensor—optical or ECG—then map the BPM to a low‑frequency oscillator. Next, feed that signal into a motion controller that adjusts actuators or electro‑chromic panels on the fabric. Finally, time‑sync the output with the show’s audio to keep the visual beat. You’ll need a solid firmware loop to keep latency minimal, but once you have the data pipeline working, the rest is just tweaking. If you keep the system modular, you’ll be able to swap out sensors or fabrics without rewriting the core logic. Good luck—just remember to test the pulse‑to‑motion conversion on a dummy first.
