Topic: MBHO (or other) rotational orientation

the example would be closer if the sun was shining on a wall directly (like a foot away) behind the window, rather than the room itself.  The included angle is a lot less than if the light was shining across the room. So as the sun moved, it's reflection on the wall would move much less than if it was shining across the room.  My reasoning is that the capsule is fairly close to the bars.  The capsule is close enough that the bars are (almost) acoustically transparent, no matter which way they are lined up.  I say almost because the fact they are there has to have some affect on the sound, but in this case I would bet it is so small that the difference is negligible.  Also light is more directional than sound.  While highs and high mids have directional properties, low mids and lows have very little.

(edited for clarity, but Im still probably not making much sense)

Reflections? Attenuation vs angle? These things are possible, or perhaps the bars could be more or less acoustically transparent and only serve to protect.
Consider a venetian blind- as the sun moves across the sky and you have horizontal venetian blinds, your light changes as the day goes on. You get a varying mix of direct and relected light into the room as the day goes on. If you have vertical blinds, and it is the equinox on your east and west facing windows, the blinds do basically nothing. Stereo sound reverses the effect- vertical blinds would be like putting the bars horizontally and horizontal blinds would be like putting the bars vertical, different time of day corresponding to different angles from the stage.

In your light example the source is in motion.  In the case of the mic, the source is constant. 
     However using your example, light is broken up into colors just as sound is broken up into frequencies.  With the blinds in place you may be getting slightly less light, but you still get the full spectrum of colors in each bit you get.  Sound is the same... you could block 1/2 the cap and you will still get all the frequencies, just maybe not as much.  So worse case scenario you need to push your levels up 1/1000th of a db!  Once again... my logic.
