The goal of this project is an incredibly simple and freeform environment for managing everyday digital life. It combines ideas from Morphic, Tunes, and the Emacs interface to provide an system in which everything can be manipulated and extending it to create your own music library/application/game/blog/whatever and understand what is going on under the hood is far less work than required under existing operating systems.
Of course, if you want a system that just works, it will be there for you; no blue-screens here.
Since this project is going to be implemented in my language, it is just in the ideas stage. When I get time I'll post more designs.
Squeak is a well-known existing Smalltalk environment and is an inspiration for this project, but at a language level lacks the security (because of the mandatory global class namespace and no built-in support for access control) and flexibility (by using class-based OOP, not prototype-based) needed at the language level.
