PILOT CONCEPT #1: VISUAL CHIME
Imagine: A street use will be reallocated this evening for functional reasons such as deliveries or sanitation, or for nighttime culture/economy reasons such as a festival, market, or other playful programming.
The Visual Chime announces the change.

Imagine
Experience from afar: A walker, cycler or micro-mobile traveler looks out into the distance to locate a intersection or crosswalk. The next intersection is clearly marked by a vertical line of light on each of the corner buildings.
Experience close-up: Pedestrians and local residents enjoy a festive or softly, cheerful immersive luminous environment at the quintessential neighborhood corner.

There are two strategies to achieve this concept, each with two luminaire types. Option A has two fixtures for cast light – for the building corner and for the sidewalk experience. Option B has two fixtures, one a solid line of light, which would be seen during partial day, and the other a duplication of A for the sidewalk.
