Line Busch (b. 1979) is a Danish visual artist. Her work takes form as persistent and repetitive examinations of transformation and optical illusions. A fascination with change, color, reflection and perspective culminates through physical disruptions in the surface of painted canvasses. The canvas frame with fixed twisted canvas cuts and acrylic paint in soft gradients or strong color surfaces is a recurrent format for her investigations of form and perception. The manual work of the hand performed when cutting the canvas entails errors and deviations in the otherwise systematic fixation of color and materials. Her abstract paintings thus appear methodical, precise, responsive, and unpredictable.

Her work with how color can convey movement and transformation carry a phenomenological aspect as it is not only constricted to the actual frame but expands into the exhibition room itself: optical illusions initiate a dance between subject and object as the viewer's curiosity is piqued and induces bodily movement to perceive each work's changes in color and form.

Busch's practice expands from abstract paintings, aluminum wall works, paint and canvas to ceramic sculptures. The sculptural objects, rigid but slightly curving, share the paintings' tactility and the theme of horizontal refractions and vertical lines but in a new rhythm.
