Several Surfaces - Soft Mirror

Prague, 25 July 1977

In a small basement room I pulled the door shut until it was almost closed and partially fixed a strip of material across the gap in the door. I placed a flat dish containing mercury on the floor in font of the door. People looked at me through the gap in the door one by one and I observed them in the mirror of mercury which I was able to shape as I wished. When they had all come and gone I put the room back how it was and left.
