Mittens

How it works
Click the mitten in the menu bar, press Lock & Play. The screen is covered on every display. Each key shows a big letter, number or emoji and plays the next note of a song. The trackpad and mouse play hand drums.
The way out
Hold ⌃ control + ⌥ option and press Q, or hold both keys for three seconds. The letter is configurable. A pill at the bottom of the screen explains this throughout.
Modes
Classic: 14 scenes, letters with words and pictures, counting, 24 public-domain songs. Hacker Typer: code rain, a terminal that types pretend code, chip-tune voices.
Limits
Not a safety, supervision or childproofing product. It reduces accidental input; an adult should stay present.
