Abstract by Design or Mistake

I was sitting on an upholstered bench and went to grab a quick shot with my phone. It slid out of my fingers and took a photo of the upholstery as it landed safely on the bench.
I couldn't believe it had actually taken a geometric abstract for me, which just happens to be the twist for today. I think the light patch must be my arm trying to grab it.
Phew, blip sorted.
