If Venetian blinds could twist and turn based on the time of day.
Believing static building facade shading options to be insufficient, architecture student Tyler Short has come up with "Penumbra," a concept for a kinetic shading system that would reconfigure based on the position of the sun.
As seen above, the system involves a series of vertical shading louvers that would independently pivot into a horizontal light shelf when the high afternoon sun strikes. With so many moving parts, Penumbra would no doubt be a pain to maintain in real life. But the concept nevertheless makes for a stunning visualization. Short created this 3D animation to show off his idea.
