Although in different ways, the two media art works Vectors (1989–1990) and LAPIS/X REDUX (2009) both comprise digital images rendered in real time through human-computer interaction based on the polarity between certainty and uncertainty. The two form a system to generate images with similar characteristics.
Vectors is produced from an interaction of images which have been rendered by computer and printer (on continuous form paper). The interaction, which translates into visible markings, is triggered by random events due to glitches in the equipment and the software. These interventions are previously or subsequently combined with printed elements by the artist. The image thus constructed is unique, contradicting the expectation of predictability and repetition normally associated with computers. Vectors aims for this inter-creation, an association of the intuitive and logical capabilities of man (“author"” and the logical features of the computer (“co-author”).
LAPIS/X REDUX Inter-image, Process and Experiment relies on hypermedia comprised of five interdependent parts – ad finem (1999- 2000), LAPIS/X (1999-2000), Lumina (2002- 2009), SC (1999-2004) and Tharsis (2002–2009) – which share the same conceptual matrix while differing in formulation. This work was devised in 1999 as a project centred on inter-relations among images (dialogues between memories and representations) in the framework of the man-machine collaboration. Hypermedia resources were chosen to present this dialogical process to the public as a remembrance of its flux. While these can neither reproduce nor be equivalent to the process, at participant level they transfigure into another process and an experiment evoking “its own memories and representations”. A labyrinth of occult and unexpected trails, it holds multiple layers of meaning. The interaction design is minimalist and emphasises the combination of determination (choice)and indetermination (simulated randomness).
