Choi Byoungil works freely in a variety of genres, including media art, sculpture, installation and graphic design. He builds programmed machines which become platforms for experience on which humans and machines respond to one another and take part in interaction. memoria technica is one of his programmed machines. Twice a day, it shatters mirrors with phrases from our daily lives painted on them. Here, Choi demonstrates his belief that memory is a pile of fragments. When memories shatter with the mirror and pile on the ground, those fragmented memories become fixed, create new meanings with other elements in presence, and transform into unpredictable variables. By fragmenting images (memories) reflected in the mirror, the artist urges the audience to view them differently, and thereby reorganizes how we perceive or make sense of them.
