Lee Bul’s Idea Sketch for REAL DMZ PROJECT is a sketch for a piece that was conceived by employing the forms of structures that were installed in the DMZ but are no longer used for their original purpose. Idea Sketch No. 2 for REAL DMZ PROJECT – Infinity Type B utilizes a watchtower-type bunker that is located near the entrance of Soyisan. It is a work in which mirror fragments in multi-angle cuts are pasted on inside the bunker so that the northern scenery of the watchtower is simultaneously reflected from various angles, showing a fragmented surrounding view that is dependent on external changes like the seasons and weather.
