Virtual Worlds Virtual worlds garnered a tremendous amount of attention in 2006-2009, when millions of individuals created online avatars and institutions were developing building after building on designated plots of virtual land. In Linden Lab’s Second Life®, world-class universities hosted thousands of educational projects and experiments, from recreating historical spaces to replicating renowned museums and works of art. A lot of energy was devoted to building tools, climate simulators, physics engines, and facilitating the overall capability of these platforms to simulate reality. The idea was that these environments could foster unique and immersive learning opportunities, doing so in a way that uniquely made people feel like that were together in the same place. While the hype around virtual worlds has waned in recent years, there are still compelling developments, mainly in the form of WebGL, a new way of rendering 3D objects in via a web browser, which has been applied in virtual worlds. CloudParty, a Facebook application, is a good example of the capability of WebGL, though it is more of a hangout space and does not have as strong a tie to learning as do other purpose-built spaces. Google is a leading player in academic WebGL technology, and its vast collection of user contributed “Chrome Experiments” range from an interactive timeline of satellite launches to a visualization of connected cells that enable people to create biologically-inspired patterns.
