A programmer turned Wikipedia into a classic text adventure
Wikipedia: The Text Adventure generates a list of major landmarks, and clicking any of them takes you to a landing page with a basic location description as pulled from its Wikipedia article summary, along with a list of nearby locations marked off by cardinal directions. You're restricted to a text box, and, appropriately, typing "help" into it brings up a list of commands you can type.
Nice collection of free animated icons.
