A short aside.
A rainbow is a portion of the base of a cone. You (the viewer) are (at) the apex of that cone. If one moves the apex by the slightest, a different segment of a different (circular) base is observed as a rainbow. That means that two people standing ear to ear, eye to eye, are viewing, literally, different (unique) rainbows!
No two people see the same rainbow.
And, as we are the 'apex' of the equation, it is us that is the metaphoric 'pot of gold' at the 'end' of the rainbow!
Now the secret's out!
