The role of light in architecture extends well beyond practical requirements. Light can create an environment, saturate a space with emotion, and compose spatial illusions. When manipulated in the right ways, light makes an architectural space livable, shapes it, and guides the inhabitant through it. As our homes and buildings become increasingly interactive and connected to the internet of things (where physical objects such as a lamp or microwave are programmed in the cloud), the creative possibilities for lighting are growing exponentially.
