The visitor (user) also called a "Brain Worker" in this context is wearing a head piece that measures biofeedback (EEG) . The "Brain Worker" is given a human value like openness and is asked to continue shape an abstract 3D form of this value by meditating around this word, hence, controlling their brainwaves. The "Brain Worker" sees real-time how their biofeedback is reshaping the model, which also feeds into the experience and alters the brain waves. After the process the final 3D shape becomes a block-chain token that can be used for bartering.
