The article describes the festival of computer-based art Cynetart as a place of artistic experiments with ‚rhythm of nature’. Artists which took part in the festival in 2015 were using matter of nature as an instrument of artistic expression. According to the author, performances and interactive installation which were presented in the festival are specific form of a continuation of Émile Jaques-Dalcroze’s and Adolphe Appia’s artistic experiments. Eurythmics and performance practice (which started in 1910 in the same place – Festspielhaus in Hellrau) invoke to eurythmics of Dalcroze and Appia’s conception of light in performing arts. Performances: Jymming by Tom Fritz, Eternal Cave by Gil Delindro and Plectrum by Kuai Shen, were also interpreted as a form of posthuman and ecological aesthetics.
