A home with walls at least somewhat aligned with solar south at local #WinterSolstic. In the bedroom and primary day-use spaces, the east, west walls and ceiling are partially or completely covered by an LED matrix, and there are a lot of light sensors.
An unreasonably complex controller tries to track the sun's position, and produce a (slider-controlled?) level of ambient (#FullSpectrum? configurable?) #light from that relative position.
