I guessed the length of an "hour" and drew a round shape on paper simultaneously.
Video was taken at the other side of the paper to see the process of ink penetration.
The differences may occur or not. I just try to catch the 24 years experience of staying with artificial time.
But, finally, no single one matched that.
I guessed and drew 8 times which is used to fit the office hours(8 hours) and turns out 6 hours, 8 mins, 4 seconds and 16 milliseconds.It became the exhibition hours of my show(12:00 - 18:08) and separated with the office hours.
