I confess I haven’t read this email carefully (I’m trying to work
through my email backlog), but this question reminds me of something I
read a long time ago, which is that the eye identifies straight line
because they are invariant under motions of the eye back and forth in a
single direction. That means that straight lines are the retinal
patterns that are invariant under a certain class of eye motions.
This works not only for lines but for straight edges. Only a skip and a
jump from there to Platonic solids. 😉

prompt: All energy in the universe is expressed in motion. All motion
is expressed in waves. All waves are curved. So where do the straight
lines come from to make the Platonic solids?
