Mason was an early computer programmer and digital artist at the forefront of computer art. He studied physics and mathematics at university, and after graduating, worked at White Sands Missile Range near Las Cruces, New Mexico. He later became the head of the Analog Simulation Lab at Thiokol Chemical Co. in Brigham City, UT, and worked at IBM for 25 years as a computer programmer. Mason was also the President of the Society for Computer Simulation.

Mason created plotter drawings and lithographs using an analog computer that were early contributions to the field of computer art. The journal Computers and Automation featured his work in its annual computer art contests in the 1960s, at a time when computers were specialized tools most commonly used in academia, research labs, or the military.
