Lively (apparently code named Fiji and Google Rooms, and previously nicknamed Google Metaverse by some outside Google) is a three-dimensional chat world by Google. You navigate your avatar to talk to others, show your emotions, and, if you want to, build your own rooms for your website. Lively runs inside the browser but needs a Windows installation first to work.

Lively was a network of avatars and virtual rooms created and decorated by its users. Google launched Lively on July 8, 2008 as an experiment in providing people with more ways to express themselves on the Web.

Lively's users created thousands of cafes, bars, discos, tropical islands, treehouses, space stations, galleries, bedrooms and more. Lively's users shared their rooms with people from all over the real world, meeting and chatting with each other via their customized avatars.
