Decade Clock consists of four concentric circles, each of which makes its way through the colour spectrum at a calculated rate.
Working like planets in orbit, all colours are aligned at the start of any decade, a combination it will take ten years to return to.
The result is a unique way to witness and reference the passing of time, divorced from calendars and traditional methods of timekeeping.
From the inside out, each ring completes a full colour cycle:
A traditional screen displays colours in RGB (red, green, blue) values ranging from 0 to 255. There are a total of 16,777,216 different RBG colour combinations.
What you see is a clock face that shows any single given colour combination only once in any ten year cycle and only for a total period of 53 seconds before the outer-most ring changes one of its RGB values and the face displays a visually subtle but mathematically different combination.
