Key Features of Squama (Programmable Architecture)

: Each "phygcell" can be toggled between opaque and transparent, allowing the surface to function as either a solid wall, a clear window, or something in between. In the context of technology and design, most

: The system can automatically darken specific tiles based on the sun's position to create shadows where needed (e.g., to prevent glare on a screen) while keeping the rest of the window clear. : Each "phygcell" can be toggled between opaque

: Using depth sensors, it can detect a person's position and only obscure the parts of the window that would compromise their privacy from the outside. Other Notable Meanings Squama Window by Jun Rekimoto & Akihito Kinoshita
