Second Life is a free 3D virtual world where users can create, connect, and chat with others from around the world using voice and text.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 places, objects and other avatars. They can explore the world (known as the grid), meet other residents, socialize, participate in both individual and group activities, build, create, shop, and trade virtual property and services with one another.
The platform principally features 3D-based user-generated content. Second Life for android also has its own virtual currency, the Linden Dollar, which is exchangeable with real world currency.
