Gadgets that actually run on the page.

Or try it with your eyes: turn on eye tracking (the 👁 Try eye tracking button, bottom-right) and the gallery reacts to where you look -- rest your gaze on a gadget and it runs as if your cursor swept across it. It all happens in your browser: the webcam never leaves the page, and the page's own rules block it from trying. Open your Network tab and watch it stay empty.
Eye tracking not an option? Flip on Head-pointing mode (for lazy eye or low vision) and aim with your head instead.
