Hypnotize is a collection of timers for your Dock telling the movie to shut up and your Mac to shut down when time is up.
Simply add the Hypnotize folder as a stack to the Dock for easy access. Whenever needed, simply fan out the stack, run the timer with the interval of choice, and your computer will shut down once time has run out. Was the movie interesting? Press 'Reset Timer', and the countdown starts all over again. Hypnotize only force quits Safari, and will halt the shutdown if any other applications with unsaved documents are running. This way Hypnotize is completely safe, preventing you from losing any unsaved data during the shutdown process. By default, Hypnotize is set to shut down the computer after 15, 30, 45 or 60 minutes, but these intervals can easily be changed in Script Editor if needed.
