Play peek-a-boo with one-way two-way mirror windows

Combined with temperature sensors, judicious flipping on and off could allow significant savings in warming and cooling the interior. On a smaller scale, it could also allow easy privacy screens in tight areas without having to cut down on outdoor light. [GT]
