The main rule of the exhibition was that its weight and volume had to be inversely proportional to the distance where it was being prepared. To send 1 kilogram or 1 cubic meter from Chile to Sao Paulo did cost just too much.
So the condition that we decided to follow, was that I had to be able to carry the exhibition as personal luggage on the flight from Santiago to Brazil and once arrived still be able to fill the whole exhibition space.
We decided to show the 10 (X) buildings I had completed by then in 10 (X) years of practice, bringing them to paper models where not one single gram of paper was lost or thrown away while going from 2D to 3D; a cut and fold operation.
The papers models were shown at the end of a beam that was sustained by a string with a needle attracted by a magnet hidden in the wall. The needle did not touch the wall, so that the exercise of sustaining a weightless object could be perceived as a question of pure force.
In addition to that, we took pairs of photographs of the 10 buildings with a 5 centimeter shift one from the other; then we mounted them in front of very economic plastic stereoscopic lenses placed within a paper folded device that allowed us to gain in a different way from that of the model, to go from 2D to 3D.
Plans and technical data were printed in a continuous 18 meter long roll, folded once arrived in a way, that it could offer simultaneously a good angle to read the information and acquire resistance.
