I agree with the content of the post, but the demonstration is bogus. Quite apart from any audio clues as to the location of the sound, you have the clues arising from the fact that you know where your fingers are. There is no obvious way to tell whether or not this extra information is used to ``cheat''. A proper demonstration (which works quite well, incidentely) would be to have a second person produce the sounds. SR
