I have returned to the grid as a base form, though I have begun experimenting with lerpColor() as a means of combining colours, as opposed to just randomly selecting hues within a range. The pixel array is the same from Scarce Burst, though with the squares enlarged to make them stand out more against the changing background. As with the previous sketch, the emitter is the location of the mouse / tap on touchscreen. I am also working on different indicators of time by dividing the framerate. I find my process to be more visually driven — alter the code to get a particular output — rather than led by just the code. The gesture is that space between.
