Abstract
A time-passage indicator device can comprise a housing, a plurality of light elements coupled to the housing, a window comprising an inner surface and an outer surface, and a processor that controls the plurality of light elements. The window can be attached to the housing and diffuse or scatter light emitted from the plurality of light elements. The light elements can emit the light through the window to form an illuminated region. The processor can control the light elements such that the illuminated region changes to indicate the passage of time. The illuminated region can have a minimum viewing angle from 0 degrees to 20 degrees, where the minimum viewing angle of 0 degrees is measured from a plane of the base surface.
