01How to use this
Try it on one computer
No account or pairing code needed for this mode.
- Open Demo display first and leave it open.
- Open Demo remote in a second tab or window in the same browser profile.
- Change the headline or a color. Put the windows side by side to see both.
- Try Blackout, then Restore.
These demo links include ?local=1. This mode does not connect a phone to another computer. Keep the display visible: a background tab is reported as hidden.
Pair a phone and a computer
An invited test. The live connection must be configured first.
- Ask Jay for the test links and separate display and remote pairing codes.
- Open the display link on your computer and enter its display code.
- Open the remote link on your phone and enter its remote code.
- Check Link, Server, and Screen before changing anything.
A TV is optional. Later, connect the computer by HDMI. A custom web address alone does not enable the live connection. Do not share pairing codes.
02What works in this test
In this version: editable text, background and text colors, gray-tone sliders, Blackout/Restore, and the harness’s connection and recovery controls.
Not included yet: worms, starfields, moving text, images/video, sound, playlists, MIDI, or the Notion connection. No pretend controls for those features.
The preview shows accepted settings—not a camera view of the display. “Server accepted” and “On screen” mean different things. Always check the Screen status.
Blackout and Restore may be refused if the screen changed while your command was waiting. Read the notice and press again. The display computer’s local stop remains the offline stop.

Blackout hides the screen without discarding its settings. For a stop that works without the network, use B or Escape on the display computer.
