Realized via neurotechnology, the immersive installation senses and reflects the audience’s state of mind through optical illusions. After the viewer dons a brainwave headset that measures her concentration and relaxation levels, she is invited to view the paintings on the walls. As her changing mental status illuminates the room with different light, the painted figures seem to emerge from the dark silhouettes and disappear into the sea, struggling to survive the ecological apocalypse engulfing them.

In different states of mind, the viewer perceives the same paintings differently, while the real appearance of the paintings remains unknown. This work plays with the audience’s visual sense, alluding to people’s subjective perception of the external reality. As one viewer controls the light in the environment, others can also see what she sees, establishing intimate connections between the self and the other.

这件互动作品融合脑神经技术，通过视错觉的形式，实时反映观者的精神状态。在体验装置之前，观者被邀请佩戴一个能够量化分析其脑电波的脑机接口。当她观看四周的画作时，她集中的注意力可以改变灯光的颜色。随着光线变幻交错，画中人物时而从黑色剪影中浮现出来，时而隐没在一片海水之中，他们面对灾难性的环境剧变，以大相径庭的方式谋求生存。

观众在不同心境下，便会看到不同情境，画面的全貌却隐匿在浮光掠影之下。人们对外界的认识也常带有主观倾向，流于表面的成见与真相相去甚远，却能引发当下宗教文化的动荡和阶级分化的矛盾。当一位观众改变光线颜色的时候，其他人也能看到他眼中的景象，在共情中反问真实与错觉、自我与他人之间的界限。
