Eunoia II is outfitted with 48 vibration pools, inspired by the 48 emotions philosopher Baruch Spinoza outlined in his book, Ethica, like frustration, excitement, engagement, and meditation.

Each speaker vibrates according to Park’s brain wave-interpreting algorithm, which transforms intense signals from Park’s Emotiv EEG headset into intense vibrations in the pools of water atop speakers.

That's so cool.
