The film explores the hierarchy of the head’s sensory organs in the process of cognition. The opening scene begins with the mouth, as it is most closely connected to earthly matters and thus occupies the lowest level of the hierarchy. The mouth is still depicted as a line drawing, while food appears as neutral white shapes. In the next scene, the combination of the nose and mouth represents a higher stage of cognition. Here, tonal values begin to appear on the forms, indicating a more complex level of perception.

The third and highest level is the eye—the emergence of vision. The eye is capable of identifying colorful, individual forms, and thus a sense of joy becomes visible on the now complete face. The final scene suggests that by the time a person acquires the experiences of cognition and is truly able to live with them, they have unfortunately grown old. The film concludes with a reflection on mortality. A face reminiscent of Christ appears and then disappears, after which the negative imprints of the face begin to re-emerge and reflect back, suggesting a new metaphysical dimension.

Spark was featured at numerous major international festivals between 1992 and 1995, winning the Mikeldi de Plata award at the Bilbao Short Film Festival, and also appearing in Kraków, Espinho, Montreal, Zagreb, and at the Hungarian Film Week.
