Jayoung Ku explores the boundaries between past and present, reality and illusion, focusing on the notion that these are not independently existing concepts but rather part of a continuous flow.

In the In the Window II(1999), the artist records himself leaving through a window and projects this onto the actual location.

He then films herself repeating the same actions over the projection, layering the past within a single space.

His body, the original and real entity, blurs the boundary between reality and illusion within the video, where multiple timeframes are compressed.

Red, Green, and Blue (2013) unravels these layers of time built up in the In the Window II.

The work recognizes the viewer in real-time, dividing their image into red, green, and blue layers that follow movements with slight time delays.

Each layer flows continuously in its own temporal frame until it ultimately converges with the viewer's present image.
