take off 2017
Ahn puts a sticker on his own whole body, and removes the sticker of the body part that he can perceive. He uses his body to create a difference between mental self-awareness and physical self-awareness, and to create a difference between his own and others' perspectives.
In this performing, Ahn took off all the things himself. But he could not take off all the things.
He thought there is no sticker, but the others thought there is sticker.
So, through this performance, he can make the question.
"Who is me who I can see, and Who is he who you can see?"
