Phosphorescent paint is painted to the surface of the circle board. The circle board is rotated by an industrial motor, and irradiated laser graphics. Trace generated by laser is recorded as virtual coordinates data at the same time generated physically on the circle board. These coordinates data is adjusted and calibrated based on rotation degrees of dynamic movement of the motor. The data adjusted will be the source for generating new physical traces.
A trace on a circle board is an entity that traverses physical and virtual concepts.
