A free screensaver website: watch the planet think
A calming, always-moving 3D Earth for a TV, a second monitor, or an OBS stream — a live screensaver powered by Wikipedia edits happening right now.
Then press F11 for full screen. Move the mouse to bring the controls back.
The Planet Thinks is a realistic day/night Earth that glows with every live edit to Wikipedia — each spark is a real change to an article about a place, drawn where that place is on the map. An auto-piloted camera drifts gently from one edit to the next, with optional generative ambient music, so it works beautifully as a live wallpaper, a lean-back screensaver, or an ambient background you leave running. It is a screensaver website in the most literal sense — nothing to install, open a tab and it runs. And nothing is looped: the scene is genuinely different every minute, which is exactly why it holds a glance on a second screen.
Use it as an ambient screen
On a second monitor
- Open theplanetthinks.com/?cinematic in a browser.
- Press F11 (or your browser's full-screen button). The interface disappears.
- Lean back. Move the mouse any time to reveal the controls or leave.

As a TV screensaver — smart TV or streaming stick
Any TV with a browser can run it: the built-in browser on Samsung and LG TVs, Silk on a Fire TV stick, or Chrome on Chromecast with Google TV. Open theplanetthinks.com/?cinematic, go full screen, and switch off the TV's sleep timer. The scene renders at your screen's native resolution — on a 4K panel it is a true 4K screensaver, not an upscaled video loop.
As an OBS "be right back" screen or stream background
- In OBS, add a Browser source.
- Set the URL to
https://theplanetthinks.com/?cinematic - Set width/height to your canvas (e.g.
1920 × 1080).
The heads-up display is hidden automatically, giving you a clean, living scene for a BRB screen, a "starting soon" card, or an intro — free, and different every stream.
A genuinely free screensaver — nothing to install
Most "free screensavers" for Windows or Mac arrive as installers, often with ads or bundled extras. This one is simply a web page: nothing to download, no account, no ads, no tracking. The code is open source (MIT), and the Earth imagery is NASA's public-domain Blue Marble and Black Marble — free in every sense of the word.
Frequently asked
Is this screensaver free?
Yes — it runs in any modern browser with nothing to download, no sign-up, no ads, and no tracking. It is open source, and the Earth imagery is NASA's public-domain Blue Marble and Black Marble.
What is actually moving on the globe?
Every spark is a real Wikipedia edit happening at that moment, drawn where its subject is on Earth. Nothing is pre-recorded or looped — see how often Wikipedia is updated for the live rate.
Does it need a fast computer?
No. It is a lightweight WebGL scene and runs comfortably on modest laptops, streaming sticks, and most smart TVs.
Does it work as a smart TV screensaver?
Yes — any smart TV or streaming stick with a browser works: open the cinematic link, go full screen, and switch off the sleep timer. There is no app to install, because none is needed.
Is it a 4K screensaver?
On a 4K display, yes. It is a live WebGL scene rendered at your screen's native resolution, so it stays sharp at 1080p, 1440p, or 4K — unlike looped screensaver videos, which are fixed files that get upscaled.
