GraphTerm is a browser-based graphical terminal interface, that aims to seamlessly blend the command line and graphical user interfaces. The goal is to provide a fully backwards-compatible terminal emulator for xterm. You should be able to use it just like a regular terminal interface, accessing additional graphical features only as needed. GraphTerm builds upon two earlier projects, XMLTerm which implemented a terminal using the Mozilla framework and AjaxTerm which is an AJAX/Python terminal implementation. (Another recent project along these lines is TermKit.)
