The BoardGame tool is a front end for programming custom boardgames. It features an easy and flexible interface to interact with the players and has transparent support for network or AI-controlled games. Through a clear XML interface, games elements can be specified. Using an easy-to-learn back-end language like Python for rule implementations makes it very easy to implement, adjust, or enhance rules that come with a game. The same back-end language can be used easily for simple or complex AI implementations.
DutchPIPE allows Web developers to make virtual multi-user "avatar" environments. Each Web page becomes an abstracted environment or location where visitors and other items on the page are visualized. This status is retained as visitors move around. A lot of real-time interaction is possible, resulting in persistent interactive page environments. DutchPIPE uses AJAX and the DOM for the browser, and it works without Java, Flash, plugins, or firewall adjustments.
