I've been thinking about this thing for a while. . . It's not going to be funny, just really gekky, and thought provoking.
(I saw this post up on Slashdot, and it got me thinking about it again.)
When I was living at The Aspect House, there was talk of really taking a hard look at Secondlife, and the club scene there. We had talked about making a model of the house, and populating it with people who could have a house party while we were broadcasting live. This was the first part.
The next part came to me one night in while I was chilling down in The Basement Labs with Employee #6817 (who's got a new album for free DL on that website) tripping for 14 hours off some research chemical that's yet to be made illegal. We designed the concept for a system that would track a subject's movement using RFID and relative location of some sensors for use with live generative music.
The third part is an idea that I first heard from Krylen over at (((AR))), and took on as my own personal wetdream: A wearable computer, with a heads-up display, and some sort of tactile interface device that would allow me to stay online 24/7, even overlay information on the adjustably-transparent display, to enhance the enviroment I was seeing.
Now, combine all 3 parts, and what do you get? You show up at a party with LIVE DJ's (or other musical act) that's being streamed live online to a rendered version of the meatspace room that you're in, wearing a computer. The computer system in the room tracks your position, and then places you in that relative position in the rendered cyberspace room. Now, there's remote avatars from all over the world in the cyberspace room, and your meatspace HUD shows their relative postion to you.
Now, who's to say that you're not all at the same party? And, with a little work, it's technically feasible.
