In a film, 1 second is 24 frames. Each frame is a picture. But when you are watching
1 second of film, you are not only watching 24 frames of pictures. You also watch the blank spaces (black bars) between the frames. We see the light, but we can't see the darkness.

I cut out all the blank spaces from a film. And then, I joined all the blank spaces
to create another "film" (a black film). This "film" is projected on the wall from a film-projector. Through it, we watch an "invisible part" of a film. The time between
them is counted as "inexistent".

The proportion of blank space and picture space in a frame (of this Hong Kong film)
is 7:13. The "black film" on the wall and in the machine are both 383cm, they are
cut off from the other 23 seconds of the film. It will be shown on every first 5 minutes
of each hour during the exhibition.

Pak Sheung Chuen for Yokohama Triennale 2008: Time Crevasse

Hong Kong (Kowloon Tong MTR Station), 29/12/2006 (12:47-16:38)

Without an appointment, I randomly selected a place and waited for a friend there. This time Jacky, a university classmate whom I had not seen for two years appeared at the chosen location at 16:38. He asked me, How did you know I'd be here?" I told him, "I didn't know but I've been waiting for you a long time."
