Writing a shell on a java application platform with the principle that "everything is a filesystem". Shell is really mininal - just enough to browse the application, launch an editor and trigger simple programs in jvm languages like js, objective-j, jython, ioke and whatever else they like. Achievements so far? I now have the beginnings of a shell, filesystem API (that was pretty simple), and a jython implementation of ed with basic functionality but some bugs. :)
