I am amazed at how versatile mathematics is as a tool, where art is concerned. Mathematics can be the subject of art, or it can be used in the process of creating art. Sometimes, both happen at the same time. I like to experiment and have used pencil, pen, pastel, acrylic, paper, cardboard, scanners, cameras, computers, printers, metals, and wood in creating mathematical artwork. Sometimes the mathematics in art can be complex, sometimes it can be simple. This year, my entry is intentionally very simple.
DA DA coins

The DA DA coins are a sequel to my DA DA dice (Bridges 2015, JMM 2016). Simplicity is the idea again, to the point of absurdity. We can call it lowbrow mathart.
Both coins come from a maple tree in my yard. Each coin has the word "DA" burned onto both sides. The outcome of a toss of the DA DA coins is a discrete random variable X with singleton sample space DADA. The probability of DADA is p(DADA)=1.
