Usually, I store my image data in 1 dimensional arrays. That brought up an interesting question : what happens if I selectively remove pixels? I used the % (mod) operator, which I always find a mystery - but which is always rewarding in rhythmic ways. There is a lot more to explore here - this idea of repetitions and degradation as well as some of the interesting side effects of removing pixels.

My favorite combination is the middle slider all the way to the right, the others flush left.
