The sweeping radar display is another piece of pure cinema. Real air traffic and marine systems have used raster displays and digital tracks for decades; the rotating green line on a dark circle belongs to equipment that has largely been retired. It remains instantly readable to everyone, which is why it survives on screen.
What it simulates
A classic plan position indicator: concentric range rings, a sweep rotating around a centre point, and contacts appearing and fading as the sweep passes them. Every contact is generated for effect , nothing is being detected.
Where it works
- A prop screen for film, photography or theatre that needs a control room.
- A background on a second display during a stream, where movement is wanted but attention is not.
- A visual for explaining how a sweep based display works, with the mechanics visible rather than abstracted.
- Set dressing for tabletop games and escape rooms.
How to run it
- Press Start fullscreen.
- Press Esc or tap Exit to stop it.
It goes without saying, but: this detects nothing. It has no access to location, no sensors and no data source of any kind. Do not present it as tracking anything or anyone.

Fake radar screen questions
Is this tracking anything?
No. Every contact on the display is generated for visual effect. The page has no access to location data, sensors or any external source.
Do real radar screens still look like this?
Rarely. Modern air traffic and marine systems use raster displays with labelled digital tracks. The rotating sweep belongs to an older generation of equipment, kept alive mostly by film and television because it reads so clearly.
