A symbiotic drawing device, making visible what is below the surface.
The resonant frequency of an electronic oscillator is influenced by the electric inductivity of the drawing surface – effectively turning it into a metal-detector. Whenever a strong deviation from the usual inductivity is detected, a solenoid pushes down the pen, resulting in a line to be drawn. The operator of the device determines the areas to be explored as well as the directions of the strokes – the environment as sensed by the device controls whether or not those movements have any consequences.
