As web designers tried to make the internet look more like the "real" world, they experimented with three dimensional online environments. This program looks at several early examples. Mark Pesci explains VRML, the virtual reality modelling language. Chris Stuart demonstrates blacksun.com, a web site that uses VRML technology. Annette Louden demonstrates construct.net, an online environment for building VRML sites. Rick Denny and Skuli Mogensen of OZ, Inc. demonstrate their 3D web tools for building avatars.
