Show HN: My Winter 2014 Mhacks Project, Glass Presentation Remote (ideas needed)

There's a video demo on Youtube here: http://www.youtube.com/watch?v=O7hgOJRF-m4&feature=youtu.be

I'd love any feedback or suggestions you might have. This is still very much a work in progress (20 hours left before I have to submit it for judging) but I felt it was at a good point to be able to share it.

I've blown through most of the ideas for the project that I had coming in so I'm looking for ways I can improve the project in the time remaining.
