Virtual world

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.

Crystalised

"Crystalised" is the debut single by English indie pop band the xx. It was released on 27 April 2009 as the first single from their 2009 self-titled debut album.

Music and lyrics

According to music critic Robert Christgau, "Crystalised" uses a musical structure similar to "VCR", "hooky ostinato riff embellished with a few subtle effects, leading to a soft vocal. The exaggerated drawl of bassist Oliver Sim precedes the more human-scale croon of guitarist Romy Madley Croft." Croft and Sim shared lead vocals, which Rachel Kowal from NPR said are "delivered in a sexy call and response fashion that is reminiscent of the duets" by Canadian indie pop band Stars on their 2004 album Set Yourself on Fire, "minus all the antagonism associated with ex-lovers."

Like most of the other songs on xx, "Crystalised" was based on an imagined romantic scenario, developed from a verse Sim had written thinking about what a fling would be like: "I hadn't really had any relationships to be working off. But I had a huge interest in life, and looking at other people’s relationships around me." He wrote the first lines of the song, including "you applied the pressure / to keep me crystalised", and shared it through iChat with Croft, who responded with her verse, beginning with "I'll forgive and forget / Before I’m paralyzed." John Colapinto of The New Yorker critiqued that "the finished lyrics, some of their best, suggest a twisted love affair, but also hint at drugs and ecological disaster."
