Halliday and Morrow referred to the OASIS as an "open-source reality," a malleable online universe that anyone could access via the Internet, using their existing home computer or videogame console. You could log in and instantly escape the drudgery of your day-to-day life. You could create an entirely new persona for yourself, with complete control over how you looked and sounded to others. In the OASIS, the fat could become thin, the ugly could become beautiful, and the shy, extroverted. Or vice versa. You could change your name, age, sex, race, height, weight, voice, hair color, and bone structure. Or you could cease being human altogether, and become an elf, ogre, alien, or any other creature from literature, movies, or mythology.
