Text Stream 6, 2020
"Recurrent Rayuela" (Text Stream 6) is a generative artwork made with the 155 chapters of the experimental novel "Rayuela" (Hopscotch) published in 1963 by Argentine writer Julio Cortázar. The piece consists of a black circular screen that shows a cube with thousands of letters from the book in a fluid, animated pool. When the screen is manually rotated by a visitor, the cube tumbles around and the letters become turbulent; after a few seconds, random excerpts from the novel emerge on screen from the turbulence. As soon as the rotation ends the excerpts disappear and the pool of letters stabilizes again.

Metrónomos
Metrónomos
2018
“Metrónomos” is a kinetic installation consisting of eight inverted nooses, which move slightly according to the rhythm of various global statistics on human rights violations. Commissioned for Mexico’s Memory and Tolerance Museum, the sculptures are presented on pedestals, arranged in a semi-circle. The frequency in which each noose, or metronome, sways depends on the statistic that each one represents: the number of forced displacements or deportations, acts of torture, cruelty and sexual violence, crimes against the environment, among others. Each noose contains the heartbreaking rhythm of a different scale, in order to materialize, symbolically, the frequency in which human rights are violated. Together, they create a chorus of sculptures activated by statistical data.

Population Theatre
Population Theatre
2016
"Population Theatre" is a scalable data-visualization theatre consisting of 7.5 billion individual computer-controlled points of light. The purpose of the piece is to create an experience that offers a one-to-one relationship between the world’s population and its data: every person is represented by a single point of light. "Population Theatre" is a platform for making data tangible, a direct representation of demographic data, and as such it can be used to create "data-dramatizations" that may help the public visualize data on political economy, cultural studies, sociology, anthropology, psychology, history, communications and other fields. People may stand on the stage and watch data performances, but they are also encouraged to walk along the corridors amongst the "rows" of monitors, physically "zooming-in" to see individual pixels, subverting the panoptic view and looking back at the public on the stage.

2015
“Zoom Pavilion” is an interactive installation that consists of immersive projection on three walls, fed by 12 computerized surveillance systems trained on the public. The piece uses face recognition algorithms to detect the presence of participants and record their spatial relationship within the exhibition space. Independent robotic cameras zoom in to amplify the images of the public with up to 35x magnification: the zooming sequences are disorienting as they change the entire image "landscape" from easily recognizable wide shots of the crowd to abstract close-ups. Zoom Pavilion marks the first collaboration between artists Rafael Lozano-Hemmer and Krzysztof Wodiczko.

Level of Confidence
Level of Confidence
2015
"Level of Confidence" is a face-recognition camera that has been trained with the faces of the 43 disappeared students from Ayotzinapa school in Iguala, Mexico. As you stand in front of the camera, the system uses algorithms to find which student's facial features look most like yours and gives a "level of confidence" on how accurate the match is, in percent. The piece will always fail to make a positive match, as we know that the students were likely murdered, but the commemorative side of the project is the relentless search for them and their overlap with the public's own facial features. The project software is available for free download so that any university, cultural centre, gallery or institution can set-up the piece. In addition, if the project is acquired by collectors, all proceeds will go to the affected community, in the form of scholarships for example.

Subsculpture 16, 2014
"Pan-Anthem" (Subsculpture 16) is an interactive sound installation where the national anthem of every country in the World plays back on a movable speaker that is magnetically attached to a large wall. The speakers are precisely arranged to visualize national statistics: population, GDP, area, number of women in parliament, GINI, year of independence, HDI and so on. For example, when the work is configured to show military spending per capita, on the far left of the wall the public can hear the anthems of countries without military forces like Costa Rica, Iceland and Andorra while at the far right they can hear Saudi Arabia, Israel and the United States, which spend more than $2,000 per person per year. If no one is in the exhibition room all the speakers are silent, but as a visitor approaches a particular set of speakers these start playing automatically, creating a positional panoramic playback of anthems associated to similar statistics.

Voice Tunnel
Voice Tunnel
Relational Architecture 21, 2013
“Voice Tunnel” (Relational Architecture 21) was an installation designed to transform the Park Avenue Tunnel in New York City with 300 theatrical spotlights that produce glimmering arches of light along the tunnel’s walls and ceiling. Participants control the intensity of each light by speaking into an intercom at the tunnel’s center which records their voice and loops it. Louder speech increases the lights’ brightness proportionally, creating a Morse-like code of flashes throughout the tunnel. The individual voices can be heard as pedestrians walk through the tunnel, on 150 loudspeakers, one beside each light arch and synchronized with it. At any given time, the tunnel is illuminated by the voices of the past 75 participants: as new participants speak into the intercom, older recordings get pushed away by one position down the array of light fixtures until they leave the tunnel, so that the content of the piece is changing constantly.

Sphere Packing
Sphere Packing
Subsculpture 15, 2013
"Sphere Packing" (Subsculpture 15) is a series of 3D-printed pieces designed to concentrate the entire musical production of a composer in a single dense multi-channel device. The size of each sphere is directly proportional to how prolific the composer was, for example the sphere for Johann Sebastian Bach has 48 cm diameter and holds 1100 loudspeakers playing simultaneously Bach's 1100 different compositions, while the sphere for Hildegaard Von Bingen only has 11 cm diameter and 69 loudspeakers. The project presents at a glance the comparative production volume of many composers. As people are a couple metres away from a sphere they hear a quiet murmur of sounds, but as they approach and put their ear up close to individual speakers they can hone in on specific compositions.
