Here are some more ideas which I don't intend to do anything about myself but which might be fun.
Any comments on these - e.g. to tell me that it's already been done - do email me

This one is not original but I don't know if it's been tackled seriously in recent times. I'm simply talking about using high resolution photography to construct an accurate 3D model of the surface of a vinyl record, and then using software to convert that to sound. This would be a project for someone who is already familiar with these kinds of photographic and modelling techniques.
Here is someone who has already done it - but only in a crude "proof of concept" sort of way, as you will appreciate if you listen to the sound samples on that page.
Surely this must have been done already... traditionally hearing aid designers have tried to make hearing aids as unobtrusive as possible. But meanwhile it has become commonplace to see the under-30s wearing big headphones in public places. Clearly it would be a simple matter to wear hearing aids and look cool at the same time, by fitting a little microphone in each of those big earpieces. Obvious.
This one is a bit naughty as it would make it much easier to take surreptitious pictures. Our mobile phones have front-facing and rear-facing cameras, but what about a camera looking out through the side or top edge of the phone?
