Prix
The Prix Ars Electronica Archive is a collection enabling search and viewing of all the submissions since 1987. The award-winning projects are documented with catalogue texts and audio-visual media. All other submissions can be searched by title/artist and displayed with year, category in list form. Please cite the credits (artwork name, artist and photographer) and only use the materials if your article is related to Ars Electronica.
Computational Expressionism
Joanna Berzowska
The constrained and stylized character of current two-dimensional digital art is directly related to the fact that most artists work with already existing tools. Programmed drawing tools are much more powerful aesthetically than traditional drawing media. A single algorithm can generate whole images or patterns whereas a piece of chalk, no matter how dark, can only trace very elementary shapes. The stylistic nature of computational tools can influence the visual nature of the art to a greater extent. Algorithms are so controlling that we must carefully choose, as well as author, the tools and the methods with which we decide to create and manipulate digital media.
The concept of drawing with computation essentially means to program what sorts of shapes the linear motion of the hand will produce. For an artist to draw computationally means that the artist defines the patterns and colors that the brush produces, defines the behavior of the brush, provides its computational attributes, using algorithms and design principles.
A computational line (representation of a gesture drawn with computational tools) has three attributes.
– The computational line has physical appearance, which can be a set of points joining two endpoints; it can be a shape, a pattern, a representation of a mathematical algorithm, a color.
– The computational line has individual behavior: Dynamic properties such as a change of color over time, or movement across the canvas.
– Finally, the computational line has behavior in its interaction with the other lines on the canvas. It can push them away with pseudo-magnetic forces, change their color, or affect their shape.

Joanna Maria Berzowska was born in Poland and has lived in Algeria, Gabon, Canada, Norway, Australia and the USA. In 1988, she was provincial mathematics champion and won the first prize in the junior division of the provincial Visual Arts competition. She obtained undergraduate degrees in Pure Mathematics and in Fine Arts, and a Masters degree from the Massachusetts Institute of Technology Media Laboratory.
