Overview
A screen lock in the spirit of laying a book face-down on your desk: it drops an After Dark screensaver (Aquatic Realm by default) onto every monitor until you press a key and type a simple password — so anyone passing your desk sees cool fish instead of your top-secret things. It is deliberately not real security; use Win+L for that.
How It Works
Lock it with a desktop shortcut or Ctrl+Alt+F; unlock by typing your password and pressing Enter (Esc closes the prompt, and it closes itself after 20 seconds of no typing). Clicks pass through to the screensaver, so the aquarium still toggles its bubble sounds. If Windows locks itself while the fish are up and you sign back in with a fingerprint, face, or PIN, the fish dismiss too — which is also the way out if you forget the fish password (Ctrl+Alt+Del → Lock → sign back in). A setup dialog sets the password and default saver, and you can point a shortcut at any module — flying_toasters, or random for a different saver on each monitor.
Current Status
A working Windows utility — a fun, low-stakes layer of privacy built on the AfterDark screensaver modules.
