Is the idea that fingers to the right will vibrate when the sound hits a certain higher frequency, and the fingers to the left will vibrate when the sound hits lower frequencies? I just pictured "listening" to Beethoven's 9th, and how much that would actually be able to convey to someone that couldn't hear.

Excellent project.

That's essentially the idea, except that the intention is to reproduce the neurological signals that the cochlea sends to the brain, so the sound information is decomposed with the wavelet transformation. Wavelets give something a bit different from a frequency band decomposition, which you would get from a Fourier transform. That said, there's no reason you couldn't send the Fourier decomposition... if you did, then you're playing with the interesting notion of giving the brain data in a way that it's never experienced before.
