Half full deals with the subjectivity of truth by playing with the common saying of a cup being half empty or half full. In one channel of the work, white vases are filling up with black liquid. Simultaneously on the other channel, black vases are filling up with white liquid. The liquids overflow, turning the white vases to black and vice versa. The two video channels of the work are situated in exhibition space so that the viewer can see only one of the videos at a time (for example projected on different sides of a wall).
