Reintroduce Prism Lighting

Whilst looking at lenses and prisms for lighting up dark spaces, I came across the concept of Prism Lighting. Essentially instead of a flat pane of glass, a glass with prisms that refract the light in different directions depending on where it strikes the glass. The interesting bits are that whilst the same amount of light is hitting the window, the room can actually feel brighter because our eyes don’t perceive light intensity linearly.

The technique fell out of fashion when we invented the light bulb, but I’m wondering if a resurgence perhaps using modern manufacturing techniques could usher in a new fashion for windows to make each and every room brighter.

Perhaps even a material that is able to change it’s shape during the day to optimize the light distribution in a room as the sun moves.
