>>3443986Here, I made thing to show the path of a shadow from a linear fly by, which is not specifically what the author hypothesizes but is a close analogue.
What is important to note, is that the shadows NEVER travel beyond 180 degrees in the linear model, the flag video alone shows more travel than that.
I'll post that one first, then I'll post one that shows the path of a shadow with a light source circling it.
