Constanting Luser uses one or more fineliner pens to create delicate traceries of fine lines that adopt the form of bizarre landscapes. Interwoven with symbols, abstract and figurative elements, the lines form complex structures that draw the observer into an interplay between reality and fiction.

The artist's sound sculptures indicate his affinity with music and his interest in instrument construction. One particularly impressive specimen is the vibrosaurus, ten metres in length, in which only brass instruments are used to create a mighty prehistoric form. The tubes are guided like lines ending at the dinosaur's feet, can be played using mouthpieces and produce an archaic cloud of sound.

The eye of the observer seeks familiar contours and tries to find its way through the labyrinth of interwoven ideas. In doing so, the observer embarks on a journey through real and fantasy worlds that merge in imaginary landscapes. Figurative elements and symbols such as the anchor on the left side of the picture underline the association with Melville's work of the same name.

In his wire sculptures, Constantin Luser translates linear thought into the three-dimensional. The delicate, parallel lines that the artist puts down on the picture base in his drawings, with a light touch and several pens used simultaneously, are also present in his three-dimensional works. Fragile, delicate brass wires are juxtaposed to form an airy sketch of space, made from parallel or reflecting lines. Insubstantial outlines are suspended in space, with additional dynamic impulses provided by thermal influences. Through the shadow they cast on the wall, they once again revert to a two-dimensional image.
