Kaamos
Kaamos is a clock displaying time over the course of a day. Time is expressed approximately, and is communicated to the viewer in a sensory way. The experience is comparable to the deducing of time by the position of the sun.

The kaamos clock uses luminosity - specifically the contrast of brightness and dimness - to indicate time. Its display is a grid made up of 720 LEDs. Every minute between midnight and noon, one LED will turn off in a random sequence. At noon, all the LEDs will be off. From this point on, one LED will turn on per minute until midnight, at which time all LEDs will be on.
The structural pattern of the grid changes with the process of increasing and decreasing. Kaamos will create new patterns everyday. This ever evolving, random LED pattern precludes the need to read accurate time, and instead creates a tangible awareness of the time that has passed, and the time that is left.

The name "kaamos" comes from Finnish, and means polar night. Kaamos occurs in the polar circle and describes the time of year where night lasts for more than 24 hours. Day and night are indistinguishable.
