There are a number of fan-made simulations/games aimed at recreating the old Apple computer interface from the hatch for use on modern home computers. These range from versions which can be viewed on websites, downloaded as standalone PC applications, widgets or based in IRC.

Most of them include the common themes of saving the world by entering the code and pushing the button after waiting for a 108 minute counter to reach the 4 minute mark.
