All 45 screens
Every tool on the site in one list. Each one fills your display, hides its own interface after a few seconds, and runs entirely inside your browser.
Full screen colors
One tap to fill the whole display with a single flat colour. Useful as a light source, a backdrop, a wallpaper or a test pattern.

Light tools
Turn any screen into a controllable light source — key light, ring light, softbox or plain torch.
Monitor & display tests
Check a panel before the return window closes: stuck pixels, backlight bleed, uniformity, banding and burn-in.
Browser screensavers
Ambient full screen animations that need nothing installed. Leave a tab open and walk away.
Prank & fake screens
Harmless full screen gags. Everything is local to the browser — nothing is installed, changed or sent anywhere.
