Although a few networked multi-user graphical virtual environments had already been constructed in the 1980s, they were specialized projects involving custom hardware and designed for particular groups of users.
In Lucasfilm's Habitat, described by its designers as a "many-player online virtual environment," a few dozen players used their home Commodore 64 computers to connect to a central computer running a simulation of a two-dimensional animated world.
Cybersex, also called computer sex, Internet sex, netsex and, colloquially, cyber or cybering, is a virtual sex encounter in which two or more people connected remotely via computer network send each other sexually explicit messages describing a sexual experience.
The players could interact with the objects in this world as well as with each other's graphical representations (avatars). SIMNET was probably the first working cyberspace - the first collaborative three-dimensional virtual environment.
Conceptually similar to Habitat but much more upscale in its graphics was SIMNET (Simulation Network) developed by DARPA (U. It consisted of a number of individual simulators linked to a high-speed network.
Ten years after William Gibson's fictional description of cyberspace cyberspace is finally becoming a reality.
More than that, it promises to become a new standard in how we interact with computer - a new way to work, communicate and play.
