Eunoia II delved deeper into Park's work with brainwave sensors with this piece, which is inspired by Baruch Spinoza’s definition of human feelings, which are broken into 48 categorizations. In his book Ethics, he describes emotions as states of mind and body related to feelings and says that all emotions are derived from three primary emotions: joy, pain, and desire. He lists 48 different forms of emotions, which include hope, fear, confidence, despair, hatred, remorse, overestimation, contempt, compassion, humility, pride, despondency, shame, benevolence, anger, etc. 

The work is comprised of 48 speakers with aluminum plates of varying size, each containing a pool of water. Using data transmitted through the Emotiv EEG headset, Park is able to translate emotions of excitement, engagement, meditation, and frustration, along with specific facial expressions, to produce specific cognitive activity outcomes.

The collected data is then able to modulate the speed, panning, and volume of sound, with intensity levels dictated by the intensity of real-time states provided by the artist. This allows the water to move unexpectedly as the mind reacts to the environment.

That allows the invisible to be given a physical form, creating an external representation of the artist.

The layout of “Eunoia II” was inspired by Gan Gyil, an Asian Buddhist symbol which means “balance.” In this work, water becomes a mirror of the artist’s inner self. So, the work aims to visually reflect the vibrations of the artist’s mind by reflecting herself on the surface of the water.

"I wanted to make a connection that our brainwaves, feelings, sound waves are all frequencies of energies. That is why my work attempts to embody this idea of giving the invisible a physical form to create an external representation of myself."
