Open Wonderland , formerly known as Project Wonderland is open source software for designing virtual worlds where you can collaborate with others. The video I have shown here is linked to other videos which explain how it works and what its capabilities are. You can also watch the 30 minute video by Nick Moore who explains it from a real world perspective and is someone who knows what he is talking about because he understands its uses, implications and application from experience. His Agile in Wonderland: Open Source in the Enterprise World was an osdc (open source development conference) presentation and so subject to peer review. Wikipedia describes Open Wonderland as :
The vision for Open Wonderland is to provide an environment that is robust enough in terms of security, scalability, reliability, and functionality that organizations can rely on it as a place to conduct real business. Organizations should be able to use Open Wonderland to create a virtual presence to better communicate with customers, partners, and employees. Individuals should be able to do their real work within a virtual world, eliminating the need for a separate collaboration tool when they wish to work together with others. Individuals should also be able to tailor portions of the world to adapt to their work needs and to express their personal style. The types of collaborations that can happen within the space include audio communication, live desktop applications of all kinds, and eventually collaborative creation of world content (both graphical and procedural).
There are problems with the entry as is explained at the top but it does help orientate your brain as to how Open Wonderland might be of use to you. Nicole Yankelovich has a slideshare presentation which explains its educational uses . There is also a very detailed academic review of it Virtual World Learning with Open Wonderland by David Parsons and there is another comprehensive analysis of its educational use here by Michael Gardner et al It is a serious and well established platform for health.
Can you download it? Apparently not. The project has appeared to have been killed and there are no obvious links to any sites where the development may be continuing. The Google group has had no posts since 2015. openwonderland.org doesn’t exist any longer nor its blog. Why has the world made such an important and useful project vanish? All that knowledge. All that potential and no indication of where it has transferred. Just lost in the ether.
