This architectural style would involve using static mirrors
to concentrate and reflect sunlight in a way that lets the
light move swiftly across and around walls just from the
natural movement of the sun.
For a basic example imagine sunlight shining directly down
a long hall, onto the wall.
Because of the angle a slight turn
of the earth creates a significantly greater movement of
the light playing on the wall.
Of course this isn't one of the actual possible styles: For
the light to be concentrated enough to be easily visible and
yet at a sufficiently oblique angle to move swiftly down the
hall it would have to be bright enough to cause rapid
sunburn. But clever use of mirrors, archways, windows,
passages, and crystals can let the sun move quickly down
the hall without burning anything.
For another example imagine the morning sun shining at a
steep angle against the ground. Shadows move much more
quickly in the morning.

||Not sure faster movement per se is desirable, but
engineering the play of light as part of the
architectural esthetic is good, and engineering
the *dynamic* play of light is better.

this. Wasn't there a spot outside the Walt Disney
Concert Hall that had to be fenced off because
the curved exterior wall focused the sun at that

If the mirrors must remain static then simply curving them inwards or outwards will have the effect of speeding up or slowing down the crawl of light.
||Engineering the dynamic play of light as part of the architectural aesthetic was done at least 5,000 years ago, in the Orkney Islands. Not with mirrors, though.
