I am currently making work about the theme of time. I noticed the shapes of shadow by the sun always changing according to the place where the sun is. I realized that time, such an abstract concept, could be expressed by concrete objects, just like sundials. Thus, I figured that children’s slides and tunnels could be the reference to show how things change over time. The length of tunnels dug by ants could be concrete images of time, as ants dig nests and tunnels over a period of days and nights.
