Google has recently introduced a service called Lively.
After downloading the application on your PC (for the moment only the owners of PCs running XP or VISTA will use it, for others it will have to wait a little) you can create your Avatar and your virtual world.

Google Lively is billed as a “chat experience” using avatars. Google says, “You’re about to embark on a chat experience in which you can communicate and express yourself using avatars in your very own space. Choose an avatar and use it to make friends and chat. Create rooms, decorate them to your liking, and make sure to invite your friends over.”

I’ve never really hung around Second Life but I want to try Lively (One never knows, but I still doubt on my addiction to this new virtual world)

I have not yet downloaded (bu will install it quickly) till then, you guys – Just Give it a try and comment your experience here.
