SINUSOÏDES exhibition compares the practice of code and plotter drawing by two generations of artists 40 years apart, Pierre Braun and Julien Gachadoat. 


Pierre Braun was born in Paris in 1961. A visual artist, teacher and researcher with a doctorate in Art Sciences, he has been practicing computer-programmed drawing since the 1980s. Taking a stand against the pioneering idealism of the Computer Art of the 60s and 70s, his creations question the impact of machine time on our sensibility, on the way we write or draw. 

He belongs to the second generation of artists who pioneered artistic exploration through code, experimenting with the emerging world of programming to transcend the traditional boundaries of drawing, establishing an innovative dialogue with the machine. From 1981 onwards, Pierre Braun practiced programmed drawing at Jussieu (IREM), before joining François Molnar's psychophysiology of perception laboratory at the Saint Charles-Paris 1 center in 1982. He subsequently met Vera Molnar, with whom he collaborated free of charge between 1984 and 1986, while continuing his research with François Molnar.

In this context, he explores the possibilities of drawing through programming, reassessing the possibilities of graphic production and questioning the creative process. His approach involves algorithms and graphics that call into question the individual mastery of creation. By examining the effects of code manipulation and the materiality of data in generative drawing with a plotter, Pierre Braun explores the limits of the process of graphic emancipation and its aesthetic potential. 

Julien Gachadoat was born in 1975, and grew up in the demomaking culture of the late 90s, an avant-garde scene of visual creation generated by computer code. Since then, he has used programming languages as a tool for artistic creation. And he has worked to democratize tools such as Processing and p5.js by teaching programming.

A contemporary of the digital revolution, he has seized on technology to explore its creative possibilities, through the practice of algorithmic drawing. 

Using simple graphic rules, he brings abstract forms to life by combining geometric elements and manipulating principles of spatial repetition. These creations take the form of series with multiple iterations, introducing the unpredictable through the use of random number sequences.

The two artists practices converge in their work around line, with a shared aesthetic of purity and monochrome. As the exercise of code has its own syntactical rules and specific constraints, their creativity is simulated, prompting them to find ways of visualizing abstract ideas within these limits.

The overall theme of the exhibition highlights specific research into the principles of sinusoidal repetition. By exploring data such as frequency, amplitude, phase and periodicity, which enable the infinite creation of compositions, they embody them in tangible form through the use of tracers.
