Since the end of the 1980s, beginning of the 1990's, much of the work is defined under the observational method of VACAT; as it were, programmatically conceived as ''missing''.
Essential is the interstice, the not-shown, the hidden, the buried. Further reference is made to the interstice as the essential element, remaining virulent in times of abundance.
