Mac OS X also takes place on an artificial ring structure. Similarities to Ringworld have been noted in the game, and Niven was asked (but declined) to write the first novel based on the series. "All in Fun" by Jerry Oltion, in Fantasy & Science Fiction, January 2009, mentions a faithful big-budget movie adaptation of Ringworld. In Ernest Cline's 2011 novel Ready Player One, one of the sectors of the OASIS, the worldwide virtual reality network that is the novel's primary setting, is mentioned as being an adaptation of Ringworld. The 1987 novel The Alexandrian Ring by William R. Forstchen takes place on a ring much like Niven's. Episode 5 of The Book of Boba Fett features a station called Glavis that is shaped like a ring and features sun shades in much the same way that Niven's does.
