I saw a very nice bright spectrum formed from sunlight on a hallway 
wall at home a few weeks ago. Couldn't think of anything that could 
have caused it. Traced the light back and it seemed to have been 
caused entirely by sunlight diffraction through the leaves of a large 
Magnolia tree in our back yard and then perhaps door and wall corners. 
Presumably a series of effective slits happened. Alas I didn't trace 
it back outside the house at the time for whatever reason and am now 
left wondering about the finer points of the mechanism. If I see it 
again I will try and make a point of hunting it down more thoroughly.
