This paper presents Pathfinder, a case study for making sound data tactile in clay, using ceramic 3D printing. Going outside the commonly used practice of generating a three-dimensional design in a CAD program, we have used an algorithm based on elementary trigonometry, which replaces each GCODE coordinate with a new one. The sound data determines an alternative path for the printer nozzle, resulting in an object with a highly textured surface. The project also demonstrates the wonderful role chance and glitch play in algorithmic processes.
