Flatland Rover is a software program that visualizes web pages in 3D. It displays 3D spots written in 3DML (Three Dimensional Markup Language). According to Flatland, 3DML requires no previous experience with 3D modeling or programming, and is as easy to learn as HTML. 3DML uses a basic building block metaphor that enables users to create 3D spaces by arranging ready made blocks into complete environments. Content developed in this format can turn Web pages into full Web environments that users want to spend more time exploring. 3DML pages take advantage of the third dimension to provide more screen real estate for images, links and information. Rover features DirectX support and support for common Web graphics and audio formats such as GIF, GIF animation and WAV.
