"Imagine a virtual world where billions of people live, work, shop, learn and interact with each other -- all from the comfort of their couches in the physical world.
In this world, the computer screens we use today to connect to a worldwide web of information have become portals to a 3D virtual realm that's palpable -- like real life, only bigger and better. Digital facsimiles of ourselves, or avatars, move freely from one experience to another, taking our identities and our money with us. "
