Very interesting
Mike for sure, thanks very much for the link. I have not seen anything quite like that as well. But from a teacher's perspective I am not fully sure I would recommend something like this to students especially while in the middle of learning about stereo mike techniques.
My gripe with it is that there are far too many options and confusion may reign looking at that too much. You can really sum up most stereo mike techniques with just a few select techniques, mic placements and mike angles and setting up etc. Sometimes having far too many options is just as bad or worse as having no options at all.
