I've always loved (and been curious about) how leaves distort the path of light waves. If I were to speculate, I would guess that maybe they... actually, who are we kidding? I have no idea, plain and simple. Anyone out there who can help?
So I'll admit that I don't quite get the mechanism, but when you combine that weirdness with the Ring of Fire eclipse that occurred a couple of days ago, what you get is a thing of beauty:
I think that the overlap of leaves, or perhaps even small notches in the edges of individual leaves, in sunlight's path acts like several pinholes in several pinhole cameras of the sort that can be used to project an image of an eclipse, or the sun. I think given the distance to the "screen" (house or patio) the "pinhole" doesn't need to be as small as an actual pinhole. When it's a full sun, you don't recognize it as a series of overlapping discs, but rather a handful of irregular shapes. But a series of crescents are far more recognizable as separate images.
