Aneta Grzeszykowska used her own body in her film Headache. Produced with the help of digital tools and set against a black background, the film shows a naked, dismembered body taking part in a type of ballet, a fight and erotic game with other body parts. The way in which the body is partitioned is reminiscent of techniques used in black light theatre where velvet curtains conceal parts of the actors, making them invisible.
