After the mirror display proved to be effective, we shifted our focus to the development of a grayscale display. The grayscale display achieves its effect by painting the opposing slopes of a mountain-shaped panel in black and white, utilizing the changing ratio of visible colors based on the angle. Initially, we had planned to achieve this through painted partitions, but due to several challenges in the process, we resolved it by applying white stickers to the black parts.

The resulting panel exhibits color changes based on the angle. 

Utilizing four by eight of these panels, it becomes possible to create displays like the one shown.
