Based on the idea of a poster generator that visually designs selected songs, a fascinating experiment was developed: an impulse from the user activates elements that design themselves. Areas of color are placed randomly, texts are inserted more or less at random, and fonts are changed in size and shape against all the rules of art. The ‘machine’ simply has no creative will! It is controlled by a parametric set of rules that have not been refined due to technical challenges. This refreshing imperfection allows the parameters of rhythm, text, and volume to give the compositions a stimulating lightness.
