This was stuck in the ground at the side of a freshly resurfaced road in Hemmant where I parked this morning.
If I take the original image and instead draw lines from the left to the right to cover the edges of the path, I get these areas that in an ideal case wouldn't be there. So it seemed a little sus, is all. But that's before I knew that just outside of the cropped area were concrete slabs with grass growing between.
(I really fired up GIMP to make an animated picture to show what I mean, haha.)
