The relevance of optical art movement in Ukraine can be observed just from the end of the 20th century. Wide opportunities of op art have found their application in industrial graphic, poster, fine arts. The Lviv National Academy of Arts became an important centre of creating new tendencies in Ukrainian art, where the experience of professional teachers is successfully combined with the ambitious goals of young artists. In particular, it is safe to note the Art Wood Department, which was able to educate many professional artists. Until recently, the main core of the Department was a member of the National Union of Artists of Ukraine, professor of LNAA Ihor Stefiuk. His author’s conception of plastic includes the filling of imagery with sacred ‘dematerialized’ content, poetry and generalization of forms, which exclude naturalness and sensibility in his sculptures. They are accepted as paraphrases in the styles of neo-constructivism, lyrical abstraction, where the author uses innovative techniques, masterfully combines various volumes, planes and different species of wood (the series Figures, series Objects, 1990’s; polyptych Limited space, 1993-1995; Vinus not sleeping, Vinus not sleeping, 1998)33. I. Stefiuk invested in the education of the future generation his philosophical vision of art wood and the new radical approach to modelling volumetric and spatial plastic. That is why it is important to mention the new generation of artists, who have managed to transform their obtained experience and have already become known not only in Ukraine but also abroad: A. Savchuk, N. Symotiuk, D. Shavala, Y. Titenkov. These are the graduates of the Art Wood Department of the Lviv National Academy of Arts, who actively work with wood plastic and successfully combine the traditions of the Lviv Art School with their innovative outlooks. Their volumetric and spatial compositions and wood plastic absorbed a synthesis of the brand new materials opening broad opportunities for shaping. Due to the findings demonstrated by the young artists in their works, the boundaries between sculpture, architecture, painting, optical and kinetic arts are disappearing that makes it possible to take wood plastic to an entirely new level. In their works, the artists emphasize the natural properties of wood as traditional artistic material, while at the same time reveal to the spectator its new visual-aesthetic and plastic possibilities34. That means that the terms ‘wood plastic’ and ‘wood sculpture’ are, to some extent, losing their traditional definition, offering a new prism of vision of volumetric and spatial art objects, which meet the contemporary artistic tendencies. At the same time, the artistic movements in this direction happen somehow spontaneously; there are no clearly defined general scientific and analytical models yet that indicate the necessity of the formation of certain theoretical basis and the development of optical illusion art in Ukraine.
