just attendend the Wonderland Wednesday meeting, first time for me in 3D chat for years. In the 90s we created a lot of artistic multiuser VRML worlds and had meetings via Blaxxun servers. After they went down there was silence but I kept looking for open alternatives, to create surreal multiuser experiences. Finally the open source Open Cobalt and Open Wonderland are good enough so I guess I will start to use Wonderland, also because I program Java but have a vague idea about Smalltalk, on which Cobalt is based.
New experience for me was the usage of voice chat, back in the 90s we had not the bandwidth for that fancy stuff, just text chat to communicate.
