Re-editing of an old project where I used SURFER2008, software developed for an IMAGINARY exhibition in 2008, to render some simple objects. Each illustrated surface is formed by points solving an equation of the form "0 = ..." where the left part is provided by the user, e.g. 0 = x^2+y^2+z^2-1 describes a sphere. I experimented with the basic shapes combining them together to more complex forms. Here, I re-edited some of the old images.
