Keep it running
The screensaver runs in your web browser, so your computer’s own settings can interrupt it. If your computer goes to its own screen saver, sleeps or locks, this one will stop. Before you launch it, set your computer’s sleep and screen saver to Never (or a long time), keep the tab open and in front, and press F for full screen.
How to change this on Windows and Mac
- Windows: Settings → System → Power (Power & battery on Windows 11), then set Screen and sleep to Never. Also check Personalization → Lock screen → Screen saver.
- Mac: System Settings → Lock Screen, then set Start Screen Saver when inactive and Turn display off when inactive to Never.
- Menu names vary a little between versions. Plug laptops in, and remember to set everything back afterwards.
Passwords: a web page can’t show or control your computer’s login screen. Turning off sleep and lock means your computer won’t ask for your password when you return, so only run it in a private place and don’t leave it unattended in shared or public spaces. If you need a password when you leave, use your computer’s own screen saver instead.
Tip: press F on the screensaver for full-screen. It hides the cursor when idle and asks your device to stay awake while it runs.
