Allowing the right amount of outdoor light into a room can be a tricky process. People are fickle.

I propose a set of drapes of which one side is polarized material 90 degrees away from the other side, and both sides are long enough to cover the entire window. This would allow the owner to completely black out the light coming into a room from outside if s/he desired, but also can produce a shaded effect which only blocks out the evil daystar partially.

Effects of one side versus the other side being drawn are yet to be determined. As a bonus, the shades are somewhat portable, so if you are in say, an apartment or dorm room you can take them with you to later residences.

But so few of my windows are circular.

Downside is it will probably make reading your LCD watch, TV or monitor impossible.

/But so few of my windows are circular./

Your windows need not be circular. These are shades, like drapes, which are completely separate from the geometry of your window, and as a bonus, are already at 90 degree polarized angles to each other.
