Kandid is a system to evolve graphical forms and color combinations. In subsequent generations Kandid creates random images. These images are proposals. You must rank these automatically generated images.
Kandid uses a simulated evolution without a fitness function. A cybernetic system has no aesthetic feeling. You select favorite images to give them a higher chance to reproduce. Over some generation you can find 'cool' looking images.
