(Pinched from boingboing) Second Life, for those of you who haven't read Neal Stephenson's Snowcrash, is the "Disturbing Singlarity of the Internet. Meaning it can't get more weird. 3d Avatars running around a 3d chatspace with AutoCAD bolted on. The result is a council planning officer's worst nightmare coupled with Mary Whitehouse's own personal hell.
And now, Andy's MarziMan idea, of taken a 3d model of your head and then using lasers to cut it out of marzipan seems to be one step closer. By the way, that link is top of google for "marziman". This company will make 3d models of your Second Life avatar. www.fabjectory.com/ How they will manage tails, ears, cat and dog faces is beyond me, unless they operate a "no furries" policy.
I tell you, Second Life is still small (under a million users, compared to myspace). I think someone could do quite well.
