SecondLife (SL) : a 3-D virtual world created by its Residents. (SecondLife, 2015) [1] OneLook
Second Life is an online virtual world, developed by Linden Lab, based in San Francisco, and launched on June 23, 2003. By 2013 Second Life had approximately 1 million regular users, according to Linden Lab, which owns Second Life. The virtual world can be accessed freely via Linden Lab's own client programs, or via alternative Third Party Viewers. Second Life users (also called Residents) create virtual representations of themselves, called avatars and are able to interact with other avatars, places or objects. They can explore the world (known as the grid), meet other residents, socialize, participate in individual and group activities, build, create, shop and trade virtual property and services with one another. It is a platform that principally features 3D-based user-generated content. Second Life also has its own virtual currency, the Linden Dollar, which is exchangeable with real world currency. (SecondLife, 2015) [2] Wikipedia

Cosma has a 3D interface that allows you to browse content spatially!

Cosma has been using the virtual world SecondLife to provide a 3D interface to Cosma since 2006.
The SecondLife interface consists of a series of virtual spaces designed around inviting metaphors.
The spaces all have hundreds of interactive objects such as animals, vehicles, rides and games.
There are also a number of "Magic Doors" that serve as portals to interesting SecondLife sites.
Most importantly, there are “Magic Windows” and other special objects that you can click on
to open a browser window that displays subject specific pages on this and other web sites.

Can people actually 'own' virtual land? (John D. Sutter, CNN)




Building content for 3D can be intimidating, but the Ivory Tower of Primitives has been doing a great job of easing people into it for a decade. It is actually easier to begin by learning how to author in SecondLife using this site and then move on to more complex authoring systems like Blender and Unity.

  • A Fresh New Community Look is Just Around the Corner! by Linden Lab Friday
    There are some exciting changes coming to the Second Life community platform! A fresh look and feel are just around the corner. In order to make this happen, and to ensure that everything remains intact when we make the changes live, we need to export existing community platform content, which - you can imagine - is a lot of data! Exports require that the forums be put into “read-only” mode during the export process.  What that means for you is that during that time you&rsqu...

  • An Important Update to the Skill Gaming Application Process by Linden Lab Feb 7, 2017
    As we blogged back in the Summer of 2014, gambling is strictly prohibited in Second Life and operating or participating in a game of chance that provides a Linden Dollar payout is a violation of our Terms of Service. However, games of skill are legally permitted in many jurisdictions, and since then we’ve seen that many Second Life users are interested in playing such games for Linden Dollars. We updated our gaming policy in Second Life at that time and opened applications for Skill Gam...
