The challenge given to me by Kali was “glue glyphs.” This is the backside of a cast cement fake stone that came off the huge anachronistic fireplace that used to occupy our living room. The “stone” has been sitting outside, so I had to wash it off, but there was some glue residue there. I’m not sure it’s very glyph-like. But it is accidental abstract art.
I posted a cropped and processed version of this in my main 365 album.
