Le Corbusier, the greatest architect of the last century, noted that 'architecture is the learned game, correct and magnificent, of forms assembled in light', demonstrating to what extent light has been prioritized in the Western tradition. Tanizaki, on the other hand, spoke of the important of shadows, of extended eaves. Rather than the light that shines directly into a room, he praised the soft light that penetrates a space after being reflected off the floor, and again from the ceiling.
...In Japanese architecture, the gentle light that passes through shoji screens serves a key purpose. It reaches right to the back of the room, so that the space feels bright, even without the aid of artificial light. The soft light filtering through the white film at Takanawa Gateway Station represents a form of light that was forgotten about by Japanese Modernism.
There is an Escher-like quality to these flights of steps, but it is the intricate net of shadows created by the roof structure of this sky-lit sculpture gallery, falling across a succession of vertical planes and reflecting back on the surface of the glass, which commands attention. Slender metal bars set crosswise between the rafters add their own animating rhythm. It all makes for a very complex visual arena in which to view art.
In my opinion, what makes a designer competent is precisely their ability to credibly justify their conclusions. If you can’t do this as a designer—no matter how successful your results are—then neither I nor anybody else can tell if you aren’t just picking things at random.
What I am proposing, then, is no less than to make a designer’s entire line of reasoning a matter of permanent record. On the surface is the familiar set of prescriptions, components, examples and tutorials, like you would expect out of any such artifact. Attached to every element, though, is a little button that says You click it, and it tells you. The proximate explanation will probably not be very satisfying, so you click on the next until you get to the end, at which point you are either satisfied with the explanation, or you aren’t.
