Radar Screen
The radar screen is a full-screen animated military-style tactical HUD — a sweeping radar arc, live contact blips, a scrolling alert log, and readouts that tick over in real time. It isn't a prank — it's an ambient "command centre" display for a desk monitor, a stream background, or a prop screen in a video.
Press F11 for maximum realism. Tap or press Esc to exit.
Installed the crack fills the entire screen — no browser bar, no tabs, no giveaway.
How to use the radar screen prank
- Tap Launch Full-Screen Prank above (or press F11 once it's running).
- Leave the device where your victim will find it. It'll look completely real.
- When they panic, tap the screen or press Esc to reveal it was a joke.
For laughs only. Nothing here installs, downloads or damages anything — it's all harmless CSS/JS in the browser. It's a staple of April Fools' Day pranks and works any day of the year. Just keep it kind — see what makes a good prank.
Frequently asked questions
Is the radar screen tracking anything real?
No — every contact, alert and readout is simulated. It's a canvas animation running in your browser, not connected to any real radar or data feed.
Can I use it as a stream or desk background?
Yes — go full-screen and screen-capture the tab for OBS, or leave it running on a second monitor as an ambient "command centre" display.
Is this a prank?
Not really — there's no punchline. It's an ambience/novelty tool, the same category as our DVD screensaver and Matrix code rain.
