This video documents an unusual discovery for an artist. We often find new results in audience interactions, however we seldom or never discover new results from interactions between two art works. Adam Donovan's work Untitled uses an array of ultrasonic speakers, that in ultra sonic terms are the equivalent of a jet aircraft, Oribotics uses ultrasonic sensors as range finders. So when then two works were installed in adjoining rooms, the discovery that the oribotic blooms were all bright red led to a question from Matthew to Adam: "that's an ultrasonic speaker right?". The resulting solution was to re-install the door back into jamb, and later, during the opening when the door was opened, we realised that the door was an aperture to allow more or less ultrasonic sound onto the oribots. At that point we decided that we'd show the work this way in future, and that we were interested in constructing a deeper dialogue between the two works.
