In case someone wants to look at a wall:

Nice find. I'm going to print this and put it on my wall.

I live in an old warehouse converted into apartments. The walls are made of yellow brick and they're nice to look at because of the variation in texture/wear/color

Honestly, looking at this photo even for one second only triggers intrusive thoughts about how badly it needs to be corrected for distortion...

But maybe that's exactly the lesson.
