3000 passos fins al blau gel

3000 passos fins al blau gel (3000 steps towards ice blue) (2019-2020) is a computer-generated animation, created in Processing, inspired by the so called Dürer's solid, a truncated rhombohedron displayed in the copperplate engraving Melencolia I, by Albrecht Dürer (1514). The project, developed by Lali Barrière, mathematician, and Eugènia Agustí, artist, during 2018 and 2019, explores the potentiality of the plane representation of a three-dimensional shape, the interaction between shape and color, and the emergence of an abstract structure from a repetitive but continuously changing projection of a polyhedron.

3000 passos fins al blau gel is a computer-generated animation that runs in real-time without any specific narrative or timeline. It is generated by both the rotation of the polygon, and the changes in color, position and shape. The polyhedron itself slowly varies in a range from the truncated rhombohedron to the cube, with a certain degree of randomness.

It presents a colored extended version of Dürer's solid, a polyhedron that mutates between a truncated rhombohedron and a cube, that slowly revolves around itself and fades with the background, challenging the perception.


lykt (2017) is a sound, visual, smell performance, in collaboration with Ferran Fages and Yolanda Uriz. It has been presented at V20, in Barcelona.


sediment (2017) is an audiovisual work, in collaboration with Ferran Fages. It has been presented at CraterLab as part of the series Ultrasons, curated by Alfredo Costa Monteiro, and at V20, both venues in Barcelona.

Genera Esfera is an interactive installation, in collaboration with Anna Carreras. It has been presented at the MIRA Festival 2015, in Barcelona.


I use Processing for my visual creative projects.

I teach creative programming with Processing since 2008, to very varied audiences, including Fine Arts schools, Engineering schools, Graphic Design Department at the public television channel TV3, in my city, Barcelona, at Fundación Telefónica, in Madrid.

Here is a list of some of my interests:

  • Generative design.
  • Particle systems and programming of physics simulation.
  • Computational treatment of color.
  • Hardware and software interaction.
  • Data visualization.

Here is a list of selected Processing resources.


A string of particles connected by springs. First particle in the raw follows a path defined by a super-Lissajous curve. It can also be distorted by mouse interaction.
The only forces acting upon the remaining particles are the restoring forces of the springs.
Animation based on the unit disk graph. The custom GUI elements allow to control some parameters such as number of nodes, distance at which they connect, transparency of the links, color.
A simpler version of this is used in a Buff gift for Ditmae 2015.
I made an automated version of the animation, white lines over black background, to be used live, in my project Blaast.
