Does anyone remember "The witches house" in 79904 with the crazy lettering on he sidewalk that surrounded the house?

I'm just curious, and it randomly came to mind. When I went to Chapin, I had a few friends that we would walk to their houses after school and there was this one creepy corner house they used to call, "the witches house". Apparently, an older woman who lived alone in the corner house from Edgar Park elementary and she had these strange markings and lettering one per cement square that made up the sidewalk around her home. I'm just curious if anyone knew what those markings were or why she was called that please?
