I'm still working on the Proteus project. (https://launchpad.net/proteus) This separates the functionality of the software from the UI and from the data format and even machine type. It will use a theme to specify a UI that will then apply to all your apps. The Nokia tablets are the primary platform for now.

I would love to have artistic people work on a UI theme. Unfortunately, I am also working full time now so progress is very slow and I can't do the UI until the c++ is further along. So if there are any c++ devs with a math bent who are looking for something to do that could really change things, think about this. As soon as I can create a UI theme I'll come back here for help on it.
