A while back I was experimenting with something akin to "syntax highlighting" with sound instead of color. The idea is to play different tones/noises depending on where your cursor is located in your code. Rough proof of concept that you can try out: http://marycourtland.github.io/AuralJS/

This was just a fun experiment - I'm not blind or visually impaired - but I imagine that the concept could useful for programmers who depend on screen readers. It could be simplified as well; e.g., adjust the pitch or timbre of the voice depending on the nesting level of code.
