Hey I love your blog! I just recently found it and it's kinda sad that you're doing a sabbatical, but I understand your reasons. :) I have question about a phenomenon I witnessed some years ago, I think it was in 2000. I was in Greece and at that time a solar eclipse occured. It was partial and something strane happened. There was a vine canopy next to me and the light that shone through its leaves turned into many little half moons. Can you explain that to me?
We all should do it at some point [sabbaticals], let’s us revisit old problems with a clear mind. But more importantly gives me time to really indulge in the things I want to study for my own pleasure.
What you saw was likely the silhouette created by the eclipse as it cast its shadow over the Earth momentarily passing through an object that would multiply the shadow.
Here it is again, this is what I think you saw:

The shadow of the eclipse and its silhouette may pass through certain surfaces that could have many little holes (like the leaves on a tree) and project the same image multiple times.
What you’re looking at are shadows created by the eclipsed sun shining through a cottonwood tree.
The gaps in the leaves create their own pseduo-pinhole camera, projecting the eclipse’s image — in this case, on their garage door. [**]
It’s awesome that you were able to experience that, take a pic if it ever happens again!
