Second Life is an online multiplayer virtual world which users enter as an avatar (virtual 3D character). Avatars can explore, build, own property, attend events and performances, socialise and even run their own business within the virtual world.
Many people believe that multiuser virtual worlds will have a profound impact on how we use the internet in the future, a 3D version perhaps ultimately replacing (or at least working alongside) the existing '2D' internet. This has potentially far reaching consequences, particularly as regards issues of identity and the shifting boundaries between real and virtual.
