Seasonal Venetian Blinds

I was reflecting on the venetian blinds in my bathroom. One feature that I enjoy about them is that they can be adjusted to reflect the light onto the ceiling completely changing the ambiance of the room and providing a pleasant "mid summer eve" feeling to the room at mid day. I reflected that a mirrored blind would amplify this effect although maybe somewhat harshly then it occurred to me that a hybrid blind could be constructed that would allow for all the features that i desired. This blind would use a reflective coating on the convex side to reflect light into the room while providing privacy, and, when facing outward, reject radiant summer heat. On the concave side a dark radiating absorbent finish would be applied. This surface would face outside in the winter to absorb radiation while the reflective side bounced heat back into the room. The intermediate settings would represent a high degree of adjustability for transparency, reflection and indirect lighting.
