“Yi-Jung-Hwan-Sang,” a theme of Kookmin university graduate exhibition in 2014, has two different meanings: one is from the computer term called Doubly Circular Linked List; that is, two consecutive elements are linked or connected to previous and following node respectively, and the first and last node point to each link, and consequently, this link forms a ring-shape. The other one is ‘double vision(fantasy)’. The graphic pattern at the center of the poster is designed to contain both meanings.
