I made a processing-sketch that shows the time using colors. i made 3 stripes of colors blending into each other, each of them cycling through the hue value of the color. then i blend between the colors.
the top color shows the hour, the middle color shows the minutes and the low color the seconds. the values start at red, blend to yellow and green, and get turcise at the half of the cycle. than they blend to blue and violet and finally back to red.
