I'd like to add to this thread that one of the most amazing things about how the human brain arranges the varied environmental stimuli around us to make our lives interesting is the way that we perceive three dimensional vision, in particular up close where it is most important for navigation and work.

I'm amazed how the brain manages to make beautiful subjective experience of the resonant vibrations of the tiny hairs and the truly crude, to my eyes, hammer and anvil smithy works found in our ears (bang bang), yes, that's hard to understand, especially, I guess, for a lover of musical pulchritude like a Sigurd Jorsalfar Homecoming March, such as I.

More than that, binocular 3-D depth perception boggles my goggles. Space! All those things in nearby space that we effortlessly accept as being there in our conscious world, hey, have you seen that in front of you, that glass of water, that folded book page, that person, that other person, that control knob, that that that?
