|Since our virtual worlds comply with the latest version of the VRML
2.0 (Virtual Reality Modeling Language) specifications and incorporate
leading-edge features for online interaction, research, and transmission,
the computers at your school must meet specific system requirements in
order to mount and run our programs.

Our programs utilize HTML-coded pages for the text portion and VRML-coded
worlds for the virtual reality portion of the experience. Both supply
interaction, and each type of information source is linked to data in the
other (e.g., from the text, users may hyperlink to other text or to virtual
worlds; and from within virtual worlds, visitors may jump to other worlds
or to explanatory text).
Our materials are viewed using the Netscape browser on files mounted
locally at your school in a manner that best suits your particular situation
(e.g., the files can be mounted on machines in a media laboratory, over
a school-wide network, or on individual machines in several classrooms).
The material is presented using Netscape's frame features, with virtual
worlds and text available and independently scrollable at all times.
