How do I write a program to automatically explore the web?

Active Worlds (AW) is a 3D virtual reality platform. The Active Worlds Browser runs on Windows, and on the majority of computers today. Users assign themselves a unique name, log into the Active Worlds virtual universe, and explore 3D worlds and environments that other users have built. Users can chat with one another or build structures and areas from a selection of objects. AW allows users to own worlds, and universe and develop 3D content. The browser has web browsing capabilities, voice chat, and basic instant messaging. This integrated software can allow users to connect, explore, and gain a more in depth understanding of 3D. Corporate and educational clients of Active Worlds can make use of the interaction, communication, and media to provide functional environments suited for their objective.
