Professor Ernste briefly talked about binaural recordings and I've been interested in it and found this today.  I've only tried the virtual haircut and that was enough.  The depth perception in terms of hearing is really interesting because it seems so pinpoint and accurate.  Anyways, I won't waste your time with more descriptions, just hear it for yourself if you have a few minutes and I suggest you use decent headphones.
