The action: After my talk I ask the audience to leave their chairs and come closer to me. Without any form of mirror, I ask them to guide me verbally to place the tattoo machine in the middle of my forehead between my brows, in order to make a mark with red ink. Eventually I hand them the tattoo machine so that they can do the final touches.
I stand in a room in the dark. The audience can enter the room one person at a time and contemplate the palms of my hands softly lit by a spotlight.
