Proposed future development..

My dad is always talking about what technical advances to the human body we will have in the future and I thought I'd propose one. I would like to get equipped with a device that would project music from me according to my emotions, like a person in a movie. When I am sad, a sad theme song would play. When I am feeling crazy, maybe a rock or techno song...you get the picture. So if anyone out there in the void of blogging is considering creating this technology, you have my vote.
