Heart Nebula
A live heart rate, captured in‑ear and breathed into a nebula (IC 1805). The image — and the number — beat at the real pulse.
How the heartbeat travels
- AirPods Pro / Apple Watch — in‑ear PPG or wrist sensor reads BPM
- HealthKit → iOS app — samples observed and forwarded
- Vercel function — validates 20–300 BPM, holds the secret
- Pusher channel — public real‑time stream
- This browser — sets the pulse period to 60 ÷ BPM
