I never considered the 3D aspect; but it makes perfect sense.*
   For me, I find that as long as the LOCATION is more or less the
   same, I can find something again.* With messy piles, I like the
   face that little pieces of everything are "sticking out"; and
   with the clues of location plus a piece of the actual item
   sticking out, I can retrieve things very quickly.

   +[3]Ulrich Baer In thinking about it, I'd say that our brains
   may store best in a slightly less than 3D fashion; perhaps 2.5D
   or 2.75D: Think about the wireframe of a 3D cube; we can see
   every point except the one that is furthest in the back; that's
   a blind spot (the "180 degrees behind") that we have the
   greatest trouble with conceptualizing. In other words, things
   "disappear" if we don't see them.* A human weakness I think. But
   we see and remember much of the way around things; certainly
   much more than 2D.* We also have Time on our side; "when" we
   last saw something.* A benefit of our Time travelling brain.* It
   might not be linear time; but certainly we can remember
   circumstances and situations that happened around the time we
   last saw something, helping in our retrieval of the object.
