kali challenged me to fill the frame with texture, grunge and patina of man-made surfaces to create an abstract . She got this idea from this photo by one of her favorites on instagram, Charles used to be on 365 https://www.instagram.com/p/CgHE6hyuNtJ/
I haven't found much patina in our metal around here, but I did get some texture and grunge. I picked this image because it has the orange/purple colors of the instagram image.
