    If you are thinking of light through heavily branched trees, that is
diffraction through "slits" formed by the branches. Rather look at the shadow of
a lone branch in winter. Better yet, put a vase in the window and look at its
shadow.

    Sunlight is quite close is quite close to parallel, being a source of about
1/2 degree in the sky.
