It is a visual diary of the emotional expressions and observation of daily life, presenting five internal monologues with their respective titles. The installation is based on and re-designed from “Crankie Box”, the traditional animation box. The five stories are condensed and exported to long-strip backlit films. The external appearance uses the concept of "Call me in 10 minutes" which echoes the reality. The subsequent plots are brought to the stage through the introduction of “dream theaters keep performing”. Titled “On My Tail”, it intends to let the viewers fall into a loop with no beginning and end. The English name "On My Tail" is a metaphor for the camera following the ongoing inner murmur of the protagonist. In fact, it echoes the relationship between the installation and image output.
