Here are some of my UI mockups from earlier on in the project..

You can probably tell it is somewhat inspired from the Android Holo theme, but I am also using aspects in my website's design too. The battery bar is inspired from an app you can get on the Android market, which I think provides nice simple visual feedback of the battery level.

I wanted to keep it very minimalistic, partly for the asethetics, but also to keep power consumption down and to reduce visible ghosting artifacts which seem to be a problem with my display.
