Something I've always wanted to do was see how accurate my singing was
by using something that provides visual cues based on pitch.
    

Along those lines, my idea is to play a note and sing with it.

Feed the note to one mono input and the singing to another mono input.

Graph the note in one colour. The singing in another that is related but 
differs depending on how far off it is. The singing will be below the note it 
is is flat, above if it is sharp. As you adjust your singing, the lines will 
get closer of further apart and the colour of the singing will change. If you 
adjust your singing so that it properly matches the note, the colours will 
merge as will the lines...
