The artist couple, Driessens & Verstappen, have worked together since 1990. They attempt an art in which spontaneous phenomena are created systematically. Art that is not entirely determined by the subjective choices of a human being, but instead is generated by autonomously operating processes. In addition to working with natural processes, the couple develops computer programs for artificial growth and evolution. An important source of inspiration are the self-organising processes in nature which continuously create original forms. Driessens & Verstappen participated in exhibitions a.o. Stedelijk Museum Amsterdam, Garage Museum Moscow, CaixaForum Barcelona, IVAM Instituut Valencia, Neue Pinakothek München, Eyebeam New York. The artists couple gave presentations at conferences such as Siggraph Los Angeles, Second Iteration Melbourne. In 1999 and 2001, their Tickle robots won first prize in Telefónica Madrid’s VIDA competition. In 2013 the couple received the Witteveen+Bos Art+Technology Award for their entire oeuvre.
