This is a bit different than I had envisioned. From the description, and the photo of what looked like a South America -shaped crack, I thought he would find cracks that sorta looked like things, then fill in details to make them really take the personality of the thing.
I’ve been seeing faces in patterns of various objects over the last couple years, and was thinking about photographing the object making the pattern that sorta looks like a face fit into a scene that would bring the face out. I need to try that, there are a couple in the house just meters away.
