This work shows the human face in a state of externally triggered resonance. Eight facial muscles are subjected to a simple on/off stimulation pattern, with a repetition period that varies gradually between 2 seconds and 100 milliseconds. At fast stimulation rates, the external input looses its precise control of the muscle contractions: resonance patterns appear which are primarily determined by the intrinsic mechanical properties of the facial muscle system. The face thus displays its own mechanical properties on the face itself. A self-portrait of the face, manifested by its eigen-frequencies: an "Eigen-Portrait".
The sound-track of this work is a direct audio rendition of the electrical signals that are applied to the face displayed on the screen.
