Inventor: Linden Lab
Ever want to build a cathedral? Underwater? Change your clothes, your face, your whole body? Fly? You can't do any of that stuff in real life, but you can do it all and more in Second Life, a startlingly lifelike 3-D virtual world now evolving on the Internet. Unlike other shared online adventures, Second Life isn't about slaying monsters or zapping aliens. It's about building things, meeting people and expressing yourself. Even if you already have a life, you may want to get a second one.
Availability: Summer 2003, for a monthly fee
