With some difficulties, but at the end successfully, the participating artists responded to these concepts:
A structure: A structure has a domain that is a collection of elements. The elements can be points, lines, shapes, particular fragments of a larger whole, etc. What makes a structure is not just the choice of its domain. Once the domain is fixed, one needs to identify some relations between its elements.
Binary relations: Relations involving pairs of objects are called binary. In an artwork there could be many natural choices for binary relations, such as larger, thinner, brighter, parallel, of the same color, of similar shape, etc.
While elements and relations of two concrete structures can be of different nature, the underlying abstract structure for both can be the same. Such structures are called isomorphic.
These graphs are isomorphic. The graph on the left
can be redrawn to look like the one on the right as follows:

Possible Worlds for Aliens: video by Paula Quinon, sound by Luis Rosa
A series of isomorphic structures documented in a stop-motion animation shows how the same relational description refers to universes that a spectator observes as very different. The structure of sequences of sounds is isomorphic to structures documented on photographs. The project explores isomorphism in a cross-modal manner. All the universes are composed from three different types of objects (described by unary predicates) organized in such a way that relations (described by binary predicates) between elements are translatable between domains.
There are 3 objects of type 1, three elements of type 2 and one element of type 3. Four binary relations are described between types of elements. There are two relations between elements of type 1 and type 2. In intended interpretations they mean “being to the left” and “being to the right”. Relations that might be interpreted as “being above” and “being below” are defined between the elements of the type 1 and the element of the type 3, and between the elements of the type 2 and the element of the type 3.
The title “Possible Worlds for Aliens” expresses our interest in exploring non-intended possibilities of interpretation of predicates and intentional differences between similar structures. It is based on the idea, sometimes explored in philosophy, that mathematics of aliens would differ from our mathematics. The presented video is our first step towards a series of multimedia installations devoted to this topic.
