Eunoia derives from the Greek word “ey” (well) + “nous” (mind) meaning “beautiful thought”. 

In “Eunoia”, I wore a NeuroSky EEG headset to measure my brain activities and translate the data into sound waves that vibrated the five dishes of water sitting atop speakers – visually and audibly expressing my state of consciousness. The intensity of the sounds mirrored the intensity of my current emotions detected by the EEG. As a result, the water responded, in real time, with different formations of ripples and droplets in unpredictable patterns. 

I was able to detect electrical changes in my brain through the use of the NeuroSky MindWave, an EEG (electroencephalogram) reader that measured brain activity frequencies (Alpha, Beta, Delta, Gamma, Theta and "Attention", "Meditation"). I wore NeuroSky Mindwave headset and stood in the center of five flat 24” dishes which contained a thin layer of water. These metal dishes were mounted on 15” speakers. When the high-qualified speakers produced sounds, they also created corresponding ripples in the water above. The data from the EEG headset was sent to Processing via Bluetooth, which was then be translated through Max/MSP and Reaktor to produce sounds. For “Eunoia”, Max/MSP code was written to calibrate the volume, pitch, and panning of the sound associated with my varying "Attention, and "Meditation" values.
