the group's activities raised interest in international art circles - and they had frequent contact with such artists as Dieter Roth, Victor Vasarely, Piero Manzoni, Lucio Fontana, and Robert Rauschenberg. New Tendencies During the period 1961–1973, five international exhibitions were organized under the title New Tendencies. They continued the development of ideas raised by Exat 51 during the 1950s, and formed part of the broader European post-informel art movement in the 1960s and 70s. They were the initiative of art historians and critics Dimitrije Bašičević, Božo Bek, Boris Kelemen, Radoslav Putar, Matko Meštrović and the artists Ivan Picelj, Vjenceslav Richter, Julije Knifer, Aleksandar Srnec, later by a group of younger artists: Juraj Dobrović, Miroslav Šutej, Mladen Galić, Ljerka Šibenik, and Ante Kuduz. The exhibitions focused mainly on neo-Constructivism, presenting artistic achievements in a wide variety of media, such as computer graphics, conceptual art, performance art and environmental art, as well as an examination of the theory and practice of connecting art with society. The exhibitions were held in a number of museums and galleries across Zagreb presenting the latest work from internationally known artists. At the first exhibition in 1961, a common theme was the investigation of the relationship between structure and surface, and the beginnings of programmed and kinetic art, a topic that was to be developed further in the following exhibition of 1963. Experiments in visual perception gave a scientific dimension, and by the third exhibition in 1965, artists were examining the relations between cybernetics and art, and events included a symposium on the topic. The 1968/69 exhibition and colloquium dealt further with ideas of information theory and aesthetics, called "Computers & Visual Research". Two new sections appeared at the exhibition of 1973 - one on conceptual art, and another entitled "Canvas". There was also a symposium on "The Rational and the Irrational in Contemporary Art". A 6th New Tendencies exhibition was planned, but never took place. An international symposium was held in 1978, along with an exhibit reviewing the artistic changes of 1966–1978. Among the most significant works are the sculptures of Vojin Bakić, the reliefs, paintings and graphic books of Juraj Dobrović, and the paintings, sculptures, and mobile graphics of Miroslav Šutej. New Media Between the years 1966 and 1974, the visual arts scene in Croatia expanded, as in the rest of the world, to include new media art. Minimal art, Pop-art and the geometric forms
