I had an idea of creating a piece in which elements are decided randomly. After some thought, I settled on rolling dice, and using the numbers generated to influence colour on a set grid. Each square in the grid was broken into four segments, and each possible throw assigned a colour.

Colours were applied following the throw, in a clockwise direction from the left segment, then moving to the next square in reading order. A 12 roll resulted in a neutral background colour. Every 12 rows, a random number loses it’s unique colour and becomes the background colour, giving the Decay effect.

This was an arduous project, involving 9,360 dice rolls! You can read about the process in more detail on the dedicated blog post.
