This is an experiment in gradually and cyclically changing the hue and saturation values of an “array of pixels,” i.e. an image. The main parameter I experimented with was the nature of the increment value to both hue and saturation: whether it is a whole number, a float, a sinusoidal value, or a simple quadratic formula.<\/p>\n
