Virtual Pets NPR's Margot Adler reports on an upcoming CD Rom that makes the Japanese"pet" seem primitive. It's called "Creatures." You get six eggs, an incubator, and a whole virtual world for your creatures. They move, eat, grow, get sick,sleep, and reproduce. You can caress and even spank the creatures, and after ten or so hours of life, they "die." The game raises complicated questions about morality and artificial intelligence (12:30).
