Wow, more amazing stuff. XMLterm is a "semantic" user interface that uses the stylesheets to create a personalized and customized layout for a GUI interface via the Mozilla engine and backend XML data. This is truly amazing.

XMLterm Description

XMLterm is a terminal emulator application providing a command line interface (CLI), like an Xterm or an
MS-DOS window. It uses the Mozilla layout engine as its front end and a Unix shell program as its back end. An
XMLterm window can display any marked-up content that can be rendered by the Mozilla layout engine,
including HTML, XML, MathML, and, in the near future, even SVG. XMLterm is implemented as a component of
Mozilla, and is currently at the alpha stage of development.

The basic design philosophy of XMLterm is that the user interface is a dynamic XML document. The user and the
computer interact by taking turns appending this document. The plain text content of the XML document (i.e.,
excluding any mark-up) corresponds to the plain text that would be displayed by an Xterm. The design goal of
XMLterm is to enable a CLI user to access many GUI capabilities in a seamless manner. To this end, XMLterm
aims to be fully backwards compatible with the Xterm.
