Proper Time is a statistical analysis and a formulaic evaluation of people’s lives in the contemporary world. Over the five years it took me to create the Made In series, I had the opportunity to meet a lot of people and hear their stories. These encounters inspired me to start my new installation piece Proper Time, which speaks to the stories I heard from people around the world. First, I conducted interviews, both online and offline, with people from around the globe. The interviews consisted of collecting information, including the interviewee’s name, nationality, date of birth, occupation, annual income and personal memories, tied to memorable meals. The information of a total of 1,200 individuals was collected. To calculate the global average, I used this collected information and statistical data made public by governments. Next, I substituted this value for the speed of light in the proper time formula actually used in physics. The average cost of a meal in relation to the global GDP was set as the standard value, 1, in my “proper time algorithm.” Calculations from individual data substitutions yielded values such as 1, 0.5, 2.5, 3.3 and 0.2 (all relative to the standard value 1). I collaborated with electrical engineers, electric circuit engineers and programmers, and used these numbers to develop a digital circuit that can control the movement of analogue quartz clocks. When a calculated value is applied to the digital circuit, the designated clock is designed to move at a particular speed. The 670 clocks installed in the Korean Pavilion’s clock room all move at different speeds, just as everyone’s life moves at a unique pace. Directional speakers are installed in the clock room, and the audience can hear people I met throughout the project speak about their stories of memorable meals.
