Apparently participating in Dan Graham’s Present Continuous Pasts(s) as a visitor you also become a performer.
I guess that made this my first performance!
From the Hayward Gallery website:
In Dan Graham’s Present Continuous Pasts(s) the visitor becomes both performer and spectator simultaneously. The installation consists of a room containing a two-way mirror, a video camera and a monitor. The mirror reflects present time, the camera records the mirror’s continuous reflection, and hte monitor plays back the recording after an eight-second delay, thus presenting, in Graham’s words, ‘an infinite regress of time continuums within continuums (always separated by 8-second intervals) within time continuums’.
