Abstract Thursday: "Patterns"

Like many people, I'm spending a lot of my working day on teleconferences at the moment. On a call this evening, I noticed the webcam struggling a little with the limited light from my desk lamp as it got dark outside. Though I try hard to avoid posting selfies, the patterns of noise gave me an idea for today's theme. I played around a bit, and liked the effect of layering a "stained glass" effect over them.
