Croquet: deeply collaborative multi-user online applications

Croquet is a powerful new open source software development environment and software infrastructure for creating and deploying deeply collaborative multi-user online applications and metaverses on and across multiple operating systems and devices. Derived from Squeak, it features a peer-based network architecture that supports communication, collaboration, resource sharing, and synchronous computation between multiple users on multiple devices. The Edusim (built using Croquet) on an ActiveBoard or SMARTBoard turns your interactive whiteboard into a 3D interactive virtual environment.
