Is this symmetrical? I took it last night, after the challenge started, but before the topic had been announced. If I retreat to the far end of the room, close one eye and hold my head at an angle of 45 deg, I can convince myself that it's on-topic.
Seriously, there's arguably an axis of loose symmetry from the bottom left corner to the top right corner, but if the consensus is that it's off topic, I'll remove it.
