/screensaver — Screensaver Toybox
Five classic screensavers on a fullscreen canvas — Matrix rain, a bouncing logo, a starfield warp, Mystify lines and a pipes maze. Everything renders locally; nothing leaves your browser.
Reduced-motion is honoured: with it on, nothing animates until you press Start. In fullscreen the controls fade out after a few idle seconds and reappear on mouse move; Esc exits.
