So good it's almost inappropriate. This is very interesting but personally I'd let it slide.

Love this.

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

Like Stonehenge

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

Wow. Can you imagine being a cave man and seeing this on your garage door?
This is how you know we created the gods.

This is more than mildly interesting. Is r/massivelyinteresting a thing? Or is it mild like spice level so r/spicilyinteresting? r/wildlyinteresting maybe lol. Just, calling this mild doesn't do it justice. Its super neat.

I'm serious that this is probably the coolest thing I've seen today and put a big smile on my face! Very cool that your garage has a built in pinhole camera, OP!

Thank you. The ironic thing was I heading into the garage to see if I had left a light on after getting things out of my car. Took me about 30 seconds to figure out what I was seeing.

Hope the rest of your day is kind to you!

I've never seen this happen in real life, what causes it?

If you think of the world as being made of dots, each dot emits light in a bunch of different directions. With the light from all the dots pouring into a big hole, it's just a bunch of light. The information for color is kind of lost to the melting pot of all the beams of light

A tiny hole only let's one beam through of each "dot", which retains the color information on the wall because it's not melding with a bunch of other rays.

It's inverted because of how the beams work. You can't have a dot higher than the hole somehow appear higher than the hole in the final image. It travels on a straight line, and thus ends up passing through the hole and landing at the bottom of the final image.
