Second Life (SL) is a virtual world developed by Linden Lab that launched on June 23, 2003 and is accessible via the Internet. A free client program called the Second Life Viewer[1] enables its users, called Residents, to interact with each other through avatars. Residents can explore, meet other residents, socialize, participate in individual and group activities, and create and trade virtual property and services with one another, or travel throughout the world (which residents refer to as "the grid"). Second Life is for people aged 18 and over, while Teen Second Life is for people aged 13 to 17.
Built into the software is a three-dimensional modeling tool based around simple geometric shapes that allows a resident to build virtual objects. This can be used in combination with the Linden Scripting Language which can be used to add functionality to objects. More complex three-dimensional sculpted prims (colloquially known as sculpties), textures for clothing or other objects, and animations and gestures can be created using external software. The Second Life Terms of Service ensure that users retain copyright for any content they create, and the server and client provide simple digital rights management functions.
People love the idea of walking into a picture and being able to walk around a tree to see what’s behind it. In a 3D world with the help of an avatar you can do just that! You can walk away from the fixed camera view, no longer passively tied to following where the film director or camera person wants you to look, instead you can look wherever you want to look. The very idea of being able to walk into a picture raises a sense of wonder and curiosity. Of course, the reality of how to achieve this brings us back to earth with a bit of a bump. To achieve such a 3D view you need to download a program to your computer, and then figure out its controls. The wonder can evaporate very quickly when people recognize they must employ tools, and considerable patience, to achieve the ‘Alice in Wonderland’ effect.
In Second life you are represented by an avatar.
What is an Avatar?
In a virtual world, an avatar is a digital persona that you can create and customize. It's you — only in 3D. You can create an avatar that resembles your real life or create an alternate identity. The only limit is your imagination. Who do you want to be?
During registration, you will have the opportunity to select a free avatar to get you started. Once you enter Second Life, there are thousands of unique clothing, hair and fashion accessories that can be found in Resident-owned shops.
