Hey people, I'm about to start my uni final year project. For this i need to create a new invention that hasn't been done before and i'm now stuck for ideas. My first idea was using a line array speaker in a home theater to increase the level at one spot for a death person... Its been done. Then i thought of using sensors for a hand tapping drum that can work as a DAW midi instrument... Been done. Can anybody give suggestions on cool, innovative, technology based projects that haven't been done (Apps, midi instruments, acoustics - anything)? They need to relate to sound!
