Visualization of the Demand for Right-Wing Extremism Index (DEREX)

This project was motivated by the rise of right-wing extremism across Europe. I created a visual representation of the state of support for extremist ideologies. 

According to sociologist Ralf Dahrendorf, “It will take six months to reform the political systems, six years to change the economic systems, and sixty years to effect a revolution in the peoples’ hearts and minds.” His words are yet again proved by the recent news of rising demand for the extreme right all over Europe. This claim is also supported by the findings of the Political Capital Institute’s Demand for Right-Wing Extremism Index (DEREX Index), which measures and compares people’s predisposition towards far right politics in 33 countries using data from the European Social Survey. Demand for Right-Wing Extremism Index tracks changes in those social attitudes that can destabilise the democratic political systems of Europe.

The top layer of the visualization is a distorted map (cartogram), created by Scapetoad. Each country’s borders are scaled by the values of the DEREX Index. These distorted borders also function as the base of the bar chart — higher demand for extremism equals deeper levels on the visualization.

The object was cut using a CNC hot wire cutter, from 6 1250x500x100 mm XPS panels.

video: interview with Ágnes Heller (10’30″)

If the viewer steps close to the hanging smart glass wall, it receives an impulse, and the wall turns from transparent to translucent. — blocking the view of the video, but not the sound. The smart glass (electrochromic glass) is controlled by an Arduino Uno, a Relay Shield and a Maxbotix LV-EZ1 Ultrasonic Rangefinder.

Defining my workflow, infographic

This infographic is an approach to map the architecture of my workflow. In every case the defined steps are in a slightly different relation to each other, but the main structure always stays the same.



Herbarium - Atlas of Herbs

The whole concept of the atlas lies in the grids of the layout. I’ve experimented with generating Voronoi diagrams using Processing and Scriptographer. In mathematics, the Voronoi diagram is a way of dividing space into a number of regions. A set of points (called seeds, sites, or generators) is specified beforehand and for each seed is a corresponding region consisting of the points that are closer to that seed than to any other. These regions are called Voronoi cells. Voronoi-like shapes and structures are common in nature. 

I’ve merged together the cell grid of the Voronoi diagram with Villard’s Figure.Villard de Honnecourt was a 13th century architect, working in France. He developed a similar principle for designing the layout of pages which he used in his own work with structures. 

A Voronoi grid system was randomly generated for each herb in the atlas. The randomness was controlled by the rules of Villard’s Figure. This kind of layout allowed me to organize the elements of the book in a slightly different way for each of the plants. This system could be applied to an endless variety of plants, resulting in a diverse-looking atlas.

For each of the herbs I created a cyanotype print. Cyanotype is a 19th century photographic printing process, that gives a cyan-blue print. It was commonly used in herbariums for illustrating the structure of the plants. I re-edited the Voronoi grid system of each plant, using Nodebox, in order to create compositions, that reflect on their anatomical structure. These compositions were later printed as negatives, than projected on japanese paper wetted with cyanotype liquid.

During the printing process we experimented with the transparency of the paper. In order to make the “cell-grid system” visible, we chose the thinnest paper possible. This translucency created a leaf-like texture as the cells are only slightly visible through the paper under direct light.

Smokescreen

The recent news about the lack of privacy and the ensuing idea of censoring oneself while messaging online made me consider the creation of an alternative that provides more privacy in written online communication.

Smokescreen is an open source application written in Processing for generating text that is unrecognizable for the most common Optical Character Recognition (OCR) software. The application generates random “pixels” overlaid text, confusing the software but not the human readers.

Proximity sensor test sheets using Arduino Uno, Bare Conductive paint and Processing

Every test sheet is painted with a different raster, resulting different sensitivity. The paint is connected to the Arduino, that sends data to Processing. The Processing app visualizes the received data.

Dead Drops Bratislava

"Dead Drops is an anonymous, offline, peer to peer file-sharing network in public space. USB flash drives are embedded into walls, buildings and curbs accessible to anybody in public space. Everyone is invited to drop or find files on a dead drop. Plug your laptop to a wall, house or pole to share your favorite files and data. Each dead drop is installed empty except a readme.txt file explaining the project. ‘Dead Drops’ is open to participation."

Paper HID keyboard using Arduino and Bare Conductive paint

This foldable paper keyboard functions as a controller for the Tyrian 2000 video game. The Arduino is connected to the conductive paint by stapler clips, jumper wires and a breadboard.
