Vivaty is at http://vivaty.com.
I'm using my Second Life avatar name, Sharcel Bellic, for Vivaty.
Vivaty's pretty sluggish on my computer using the Flock browser. Too sluggish for someone who lacks a special interest in virtual worlds, 3D social networks, etc. to want to use it.
The Vivaty avatar is pretty ugly. No offense intended
Vivaty closed long ago. Today on March 4 2013 I finally removed the Vivaty embedded viewer that has screwed up the display of this post for years now.
I'm not sure how well the embed code will work in blog post.
