A virtual world or massively multiplayer online world (MMOW) is a computer-based simulated environment populated by many users who can create a personal avatar, and simultaneously and independently explore the virtual world, participate in its activities and communicate with others. These avatars can be textual, two or three-dimensional graphical representations, or live video avatars with auditory and touch sensations. In general, virtual worlds allow for multiple users.
The user accesses a computer-simulated world which presents perceptual stimuli to the user, who in turn can manipulate elements of the modeled world and thus experience a degree of presence. Such modeled worlds and their rules may draw from the reality or fantasy worlds. Example rules are gravity, topography, locomotion, real-time actions, and communication. Communication between users can range from text, graphical icons, visual gesture, sound, and rarely, forms using touch, voice command, and balance senses.
Evolution is a collection of short stories that work together to form an episodic science fiction novel by author Stephen Baxter. It follows 565 million years of human evolution, from shrewlike mammals 65 million years in the past to the ultimate fate of humanity (and its descendants, both biological and non-biological) 500 million years in the future.
The book follows the evolution of mankind as it shapes surviving Purgatorius into tree dwellers, remoulds a group that drifts from Africa to a (then much closer) New World on a raft formed out of debris, and confronting others with a terrible dead end as ice clamps down on Antarctica.
Evolution is the tenth album by progressive rock band Nektar, released in 2004. It was the first Nektar album since 1977's Magic Is a Child to feature original drummer Ron Howden, who rejoined other founding members Roye Albrighton and Taff Freeman.
Xcalibur is a spinning thrill ride at Six Flags St. Louis, that opened in Spring 2003.
Before being built at Great Adventure, Xcalibur was used in carnivals in Europe.
Xcalibur was announced at Six Flags Great Adventure as Evolution, for the 1999 season along with 24 other attractions, known as War on Lines. Evolution was supposed to be built in Movietown but later the ride was built where Fantasy Fling was located in the Fantasy Forest section of the park. Before it opened the ride went through rigorous testings and state inspections. Since Evolution opened the ride faced multiple problems with operations on the control panel that few can operate. Just after four seasons at the park Evolution was removed and relocated to Six Flags St. Louis. Currently the new Fender Benders (bumper cars) are currently being constructed at the former site of Evolution and opened in Summer 2012.
Evolution was relocated to Six Flags St. Louis and opened at the Missouri park in Spring 2003 as Xcalibur. During the relocation Xcalibur received a better control panel than before and enhanced Medieval theme elements. Also each of the 16 gondolas received a sound system where the ride operator can talk during the ride and play theme music. The ride is currently operating.
