aDiatomea is an artificial life system that uses various methods and notions of a-life research. The basic principle of aDiatomea is that every aspect of it is entirely mathematically generated and thus it is not created purposefully as an art piece but as a complex system that takes a life of its own. These artificial organisms are based on actual unicellular organisms known as Diatoms. These beautiful microscopic creatures are constructed using the superformula, an equation that can reproduce organic forms. Granular sound is injected in these organisms, acting as their life-force, while they interact with each other and their environment. This film shows a recording of 36 seconds of evolution in 5 different colonies of artificial diatoms, pushing the boundaries of complex computer calculations.
