Demo Matrix
See the broader system, not just one playground.
The gallery maps runnable and source-backed demos across platforms, payload types, hardware, and online workflows.
The public demo is pinned to demo.text.basic so the sketch below always responds. Switch to Use your own key to test any other project or channel.
Start the public demo to begin receiving messages.
Browser p5 Demo
Live visual pub/sub sketch
This sketch listens on demo.text.basic and turns incoming messages into a live signal field. Incoming coordinates now bend the existing network toward each event.
Binary Lighting Demo
Browser DMX publisher
Publish a binary DMX frame from the browser to demo.lighting.dmx, then let the Node bridge forward it to an Art-Net fixture or node.
