E-volver Formulae, reliefs (2017) is a series of unique bas-reliefs, that are developed with a special version of the Formulae-E-volver breeding software. The software composes mathematical formulae from elementary building blocks and visualizes them in the form of a bas-relief (height 5 mm.). The formulae for the reliefs are bred by the artists and the results are executed with the elevated printing technique (Océ Canon) in full colour acrylic. Each relief is presented in a maple wood frame without glass, dimensions: 49 x 34 x 3 cm.
