This brief article gives a description of the Open Croquet Project and its applications. The project's Web site describes Croquet as a "combination of computer software and network architecture that supports deep collaboration and resource sharing among large numbers of users within the context of a large-scale distributed information system." One of the key characteristics of Croquet is its ability to create personal information spaces as well as linkages to the spaces created by other Croquet users. Any networked information resource, including the Web, can be part of a Croquet space. Designed as a three-dimensional environment for collaboration, Croquet was initially developed with educational applications in mind, though it may eventually have uses in many other areas.
