Kaspar Dejong's work explores signs and symbols as essential elements of communication, following the semiotic tradition. By decontextualizing and dissecting everyday signals, Dejong questions their original meanings. His fascination lies in the human urge to leave a mark, observing how individuals interact and adapt in response to sensory inputs. Coming from a graffiti background, Dejong investigates these urban markings and incidents; his installations often incorporate found materials and natural elements, collected during his city wanderings. In his paintings, disrupted by colored dots, numbers, and letters, Dejong creates an abstract language through scratches and partially erased forms. Using spray paint, graphite, oil, and acrylic, he builds compositions starting with letters and numbers, resulting in an unfamiliar visual vocabulary that challenges viewers.
