OpenSimulator is an open source multi-platform, multi-user 3D application server. It can be used to create a virtual environment (or world) which can be accessed through a variety of clients, on multiple protocols. It also has an optional facility (the Hypergrid) to allow users to visit other OpenSimulator installations across the web from their 'home' OpenSimulator installation. In this way, it is the basis of a nascent distributed Metaverse.

Activeworlds hosts a Universe of over 500 3D virtual reality worlds. In these worlds you can choose from a vast array of avatars that fit your personality (or your perceived personality - that's half the fun!). You can then move about, play online games, shop and make friends with people from all over the planet. You can even stake claim to a piece of land and build your own virtual home, mansion, estate or castle! If you like to travel, there is plenty to explore.

Imagine a virtual world where you, the user, are an integral part of its evolution, where you can meet and interact with countless individuals who share similar interests as you. Imagine a virtual world you can access wherever you are.
