while wondering in Google labs I found a new service / application that they are working on that just came to the public called Google Lively - yet another virtual world that allows you to create worlds / rooms and keep in touch (chat) in 3D with other people.
It has many GUI features like adding furniture, clothes, etc
Guess what it uses Microsoft SilverLight .... just kidding.
I have created a new room called "Israel Software Architects" see you their :)
* one thing that amazed me is that the URL doesn't contain Google in it - Strange
