Weird light

[Chunk]

This afternoon I noticed this weird light pattern coming through the slits in the nearly closed blinds in my bathroom. It looked almost like a diffraction grating but I think the scale is too large for that. I think it was from the sun shining through crossing branches in a tree in the backyard with the resulting holes between the branches acting like the opening in a camera obscura. Since the angles from the holes between branches to the blinds varied, the cast images of the sun did not quite line up. As you can see, shadows cast are jagged.
