INVERTING GRAVITY 2009

Inverting Gravity is a quick exercise developed around the themes of ‘Digital Ecology’ and ‘Morphogenesis’. Having ‘Light’ as the main brief, the project combined both themes in developing an interactive installation as means of communication between the physical and the digital environment. Aiming to inform the morphogenetic programming side of the project through physical computing, the main concept is of an adaptive structure animated by light. Designed as a kinetic canopy, in order  to provide a maximum shadow area, the structure constantly changes shape according to the position of the sun.

The real-time simulation is supported by a set of physical models of the structure equipped with light sensors which interpret the position of an artificial source of light and transmit it to the computer through an Arduino board. As a result, the virtual structure changes shape interactively, according to the position of the light source and level of lighting of the real physical models. Based on Gaudi’s catenary principles, the morphogenetic side of the project is organised around  a generative algorithm that uses particle-spring systems in order to define the canopy’s self-organizing structure shaped by gravity and light. The project was developed in Processing and Arduino.
