I tried my hand and coming up with a paint brush and paint, and
attempting some story telling on the concrete outside of my house! (I
haven't played in the mud in decades.) The images are attached.
The paint brush is a fresh twig. I frayed the end by chewing on it
so that it would hold some of the paint material. The paint is just some
of the red mud, water, and some ashes from our fire-pit. The painting
is story of my girlfriend of 5 years, when
she flew out here from Colorado.
