YT-I took pictures of my creating this project, so that I could later assemble them into this video. I sketched out some rough circuit block diagrams (read: not exact, merely demonstrative) to convey my approach, and linked some good sites to obtain more info.
The original prototype board can be seen here: http://youtu.be/oKPUU21ReZg
This link also contains a vast amount of information such as motivation/inspiration, similar projects by others, and more on components used.
Final Project, extended demo: http://youtu.be/OLfF4b49MLs
If you have any questions, please hit me up; there very well may be a mistake you could discover that I missed. Outside that, I can clarify a few things, but the information and links included in the video should be sufficient.
Final words: there are so many ways this could be improved that I encourage those interested to expand on the ideas, and share!
