Shape-Shifting Home Follows The Sun

Treehugger have an intriguing post about a self-rearranging home that gradually alters its configuration with the changing weather and time of day. 

"A small channel in the floor has stopped streaming cold water, and now appears to be releasing steam. Presumably this is was intended to add a dash [of] humidity and warmth to the room"

It's not just minor features that react, it's whole walls too – shifting to maximise the sun or keep out the wind.  Each change is heralded by what they describe as "small audio clues", hopefully not of the sort that trucks make when reversing. 

I'd love to hear some more details about this, if anybody has them?
