Lived in this house for decades and this is the first time I've ever seen the "pinhole camera" effect from a gap where two garage panels come together.

When I was a little kid some mornings I'd get into my parents bed. They had these thick brown curtains that blocked out all the light from the street below. At the top of the window where the two curtains intersected the light from the street was projected onto the ceiling and you could see everything going on down there. I used to lie there next to my mom, watching the projection and we'd point out "there goes a blue car", "there goes a yellow bus" etc. It was super cozy.

I had the same thing in my bedroom. I could see the cars that were going by on the street below when their images were projected on the ceiling. It was really cool to watch.

It might only happen 2x a year at that particular hour

What’s the logic behind that?

In my experience, once you have the right conditions all it takes is a bright and sunny day. It looks like blue skies where you are. It should work at all sunny enough parts of the year.

Angle of the sun to the pinhole

No, you don’t have the sun aligning with anything here. It’s just bright outside.
