I'd like to hear more about this UI. Is it something that tuns on top of Linux or windows as a desktop environment or window manager? How do you interact with programs (all text based)? Assuming grandmas can use it, the paradigm will be easy to pick up fast? What's the syntax like if it's meant to be used widely? I'm always interested in learning about new computing UX paradigms, there are always ways to improve things!
