There are an increasing number of multi-user shared VR worlds on the Web. In these, an avatar, e.g. a photo or cartoon, usually represents the user. You can move around the 3D world and chat to other users. Some may provide simple animations e.g. to show expressions or movement. QuickTime VR allows you to 'stitch' together a sequence of images into a 360-degree view, which the user can direct.
Enhancements are likely to include stereo sound, animations and zoomable object movies.
Panoramic imaging and VRML are combined in RealSpace's RealVR browser. This supports a new node type, Vista, which is a scrollable dewarping background image. Scrollable 360-degree scenes are also support in a number of other VRML browsers. Although previous versions of HTML have allowed images to be included through the IMG element, they have not provided a general solution to including media. Style sheets will be fully supported in HTML 4.0, and may be designed to be applicable to particular media - e.g. printed version, screen reader.
