Glassworks and Sónar illuminate Barcelona with 'Analema'

Within the framework of the Barcelona Nadal Festival, Sonar has presented 'Analema', a huge luminous cylinder of interactive Led screen from the creative studio Glassworks, that can be visited 16 al 29 December in this city.

The spectacular multimedia and interactive light column He was heavy, developed by the creative studio Glassworks and presented by Sonar, will illuminate until the next 29 December Barcelona as part of the Swimming Festival, which invites you to explore the annual path of the sun and celebrate the winter solstice through this audiovisual installation.

He was heavy It is a huge luminous cylinder with a Led screen, of 6 meters in diameter and 3 high, divided into twelve sections by way of robotic prisms what, when crossed by light, reveal a great amalgamation of colors.

Located in University Square (university square), This large-format work has, in addition to the circular Led screen, with a generative sound system that reacts based on the user's position, reproducing the sound space created by the musical duo Stuffed Cake, who will also participate live on the day 16 when it opens and the 21, coinciding with the winter solstice.

Specifically, This audiovisual installation has twelve compositions in twelve tonalities, sung in different languages by Stuffed Cake, in each of the prisms, created to offer different sound environments.

“For our laboratory, He was heavy "It goes beyond a simple large-format interactive installation," he explains. Xavier Tribó, director de Glassworks-. “It has been a unique opportunity to experiment with real-time algorithms based on the physics of light and time.”.

As this manager emphasizes, “We are very proud of this proposal sensory perception about light. We invite everyone to discover different visual and sound spectrums depending on their position and time of day. This is an experiment on the winter solstice controlled by generative algorithms”.

In this sense, It will be the citizens and the visitors who, with your movements during the day walking around and that are transformed into data, generate the final choreography of light and sound that the installation emits towards the sky of Barcelona every night, that can be seen from different points of the city.

The public will be able to interact live with the installation, that will capture the movements, will transform them into data and convert this information into light and loops musicals, that will be synchronized with the vocal samples prerecorded by Stuffed Cake.

Analema will operate daily, from the 16 al 29 December, from the 11:00h until 23:00h, and will experience two different states: during the day recording the movements of pedestrians who visit the facility and transforming them into data and, at night, Each interaction will cause one of the light sources in the installation to be activated., so the attendees will be illuminating the skyline of Barcelona with its presence and movement

So, in the section of 21:00h a 23:00h a large column of vertical lights will be projected into the sky, offering a choreography, result of all interactions recorded during the day. Thus, Every night's experience will be unique and unrepeatable.. A five-minute exhibition that will be repeated every quarter of an hour and can be seen from different points of the city..

The name of the installation refers to the analemma, which is the curve that the sun describes if its position is captured every day of the year at the same time from the same point of view, which is in the form of a number 8, since the position of the sun varies every day due to the tilt of the Earth's axis.

In the time of the Greeks, The word analemma referred to the pedestal that supported a sundial. Nowadays, gives name to this artistic and interactive exploration of the solar path.
