iScape, short for information landscape, was something interesting, lost in time because it was commerical. It offers users to manage their information in a 3D space, creating a digital palace.

The iScape world is a multi-modal, multi-user, collaborative 3-D virtual environment that is interconnected with standard web pages.

This paper presents iScape, a shared virtual desktop world dedicated to the collaborative exploration and management of information. Data mining and information visualization techniques are applied to extract and visualize semantic relationships in search results. A three-dimensional (3-D) online browser system is exploited to facilitate complex and sophisticated human-computer and human-human interaction.

I had similar ideas, twenty years later, but never actually started implementing them because it's damn hard.
