A real-time biometric visualizer for the Muse headband — raw EEG brainwaves, heart rate, and head motion streamed over Bluetooth straight into your browser. Free and open source; your data never leaves your machine.

• Connect — press Connect EEG and pair your headset. Muse (Muse 2 / Muse S) is currently the only supported EEG device, and Web Bluetooth requires Chrome or Edge.
• Music is optional — upload a track (↑ Music) or switch on the Microphone to add a real-time EEG–music entrainment analysis. Everything else works in silence.
• Scrub freely — the session records itself as you go. Drag the timeline to replay any moment, or stay parked on ● LIVE.
• Save & reload — ⏺ downloads the session as a .jsonl file, and ↑ Recording loads one back in for review — no headset needed.

◉ Helix — an experimental 3D view of the same session: the last minute of EEG braided into four glowing strands, your heartbeat as a pulse traveling along the coil, signal complexity winding it tighter, and head movement swinging and spinning the view. Toggle it once a session is running.
