In this project I sought to generate images that were not the direct result from the intentions of an author, from the determinations imposed by a subject, result of applying formulas that are a simplified way to understand our phenomenal world. Simplified as they are developed upon assumptions no longer criticized, which unfold logically from models that are too abstract.
The graphic production made here emerges from the interplay of thousands of units, the connection, exchange of information. It cannot be analyzed by statistical percentages, because it is a momentary consequence of the environment in which it is inserted.
For that, I developed a software that allows the interconnection of an ecosystem of units with graphical behavior (color, saturation, size, transparency …). That works on a multi-touch screen, also developed and built for this project, allowing a natural and indirect interaction in a graphical environment, influencing the algorithmic units from the software and creating an unexpected beauty, images cohesive, complex and organized.
This project mainly uses the following software: Processing, CCV

The multi-touch screen designed for this work, is a solution that allows natural touch interaction between multiple users and the emergent software. Having been refined in successive experiments and prototypes it allows a very quick response, due to a structure of specific hardware and software that run at 60 updates per second.
The assembly has a acrylic glass with infrared LEDs around it, a translucent paper as a surface diffuser for the projected image, a câmera sensible only to infrared light and a projector. The infrared light keep reflecting inside the acrylic, here a snapshot form the camera below the glass shows only a black image.
When you touch the acrylic, because of the frustrated total internal refraction, the LED beams get out straight down, the camera sees a white dot in the shape of the finger. A image analysis transforms the white dots in cartesian coordinates that feeds my graphical software ‘Units’. The result is projected back in real time on the surface been touched, the projection and the infrared don’t disturb one another because they work in different light spectrum’s. Silicone is applied between the acrylic and the translucent paper, to better the touch sensibility, more on that later.
This project was based mainly on ideas and propositions from: Jeff Han, NUI Forum

Along with the digital experiments were also performed experiments with colored stickers.
Starting with a white sheet, I passed through different people, one at a time, each one could interact with the piece of paper placing or taking off colored stickers. Following those limitations: only two movements (moving, placing or taking off) per person. More than 150 different people cooperate, the composition that emerge is shown below.
