If you've managed to get through the day without having been completely transfixed by a 3D animation video that depicts a conceptual blind system coming alive when the afternoon sun reaches a certain altitude, well, here you go. But a warning: these aren't your grandmother's venetians. 
Tyler Short is the architecture student behind Penumbra, a "kinetic and mechanical solution to a problem that would otherwise be nearly impossible to solve with static architectural components: providing shading across a building facade for both low evening sun and high afternoon sun conditions." Essentially, the system consists of vertical shading louvers installed on the facade of a building. Not terribly exciting. But when the sun hits its highest point in the late afternoon/early evening and vertical shading is rendered pretty much obsolete, the louvers spring into action and pivot to form a sort of "horizontal shading element and light shelf" that betters blocks the sun.
Again, Penumbra — or "partial shadow," a word used to describe the lighted area around the shadow cast by the moon or by a planet during an eclipse — is just a concept at this point. But you never know — maybe some day in the not-so-distant future you'll witness entire city blocks "doing the wave" at 4pm sharp.

The Penumbra shading system doesn't just offer optimum protection from the sun — it's also totally mesmerizing to watch in full undulating action.
