What is a Rickroll?
A Rickroll is a bait-and-switch internet prank that began in 2007: someone shares a link disguised as something else, and clicking it instead leads to a famous 1987 pop music video. Tricking someone this way is "rickrolling" them. This screensaver recreates the bait-and-switch joke as a fullscreen browser toy.
Does it use the real song or video?
No. To keep it copyright-safe, this is a 100% original parody. The music is an original 80s-style synth loop composed in the browser with the Web Audio API, the dancer is a hand-drawn cartoon (not anyone's likeness), and the on-screen lyrics are original joke lines. No copyrighted recording, melody, lyrics or footage is used.
Why is there no sound at first?
Browsers block audio from playing until you interact with the page. The sound kicks in the moment you take the bait and click — that's also the "gotcha". You can mute it or adjust the volume any time.
How do I make it fullscreen?
Once you've been rolled, click the stage again or press Enter Fullscreen. Move the mouse to show the exit button, or press Escape to leave.
Can I prank a friend with it?
Yes — that's the idea. Send them the link, let them click the disguised card, and enjoy. It's a harmless web page; nothing is downloaded or installed.
Is it free?
Yes, completely free. No account, no ads, no watermark. It's one of the free browser-based tools at jasperbernaers.com.
