The play Invisible by Maja Pelević performed by Theater of Virovitica and Puppet Theater Zadar directed by Nikola Zavišić is graduate exam and the topic of graduate work by Goran Vučko under the mentor doc. dr. art. Maja Lučić Vuković at the Academy of Arts in Osijek at the Department of Theater Art, Acting and Puppetry. Graduate work begins with the biography of the text author Maja Pelević, the award-winning Serbian drama author, followed by the analysis of the text by chapters, which had been prefixed with the text. Goran Vučko's work on the performance began with the analysis of the rehearsals and rehearsal methods that were unusual for his experience so far, expanded his understanding of puppetry and were very inspirational for him as the young artist. Vučko points out that the visual elements of the play had also greatly influence the development itself and the poetics of the play, especially the silicone LED puppets, the reflection of the light on the white cloth, the costumes of the parents.He explained his own work through all the puppetry techniques and methods used in the play. He described the work with silicone LED puppets, light and shadows, UV technique, hanging pictures, and metal constructions. Vučko thinks it is important to refer on work of each of the colleagues he had worked with on the performance, because their creativity directly and indirectly influenced his own creativity. At the end of his work, he concludes that the play Invisible is difficult to categorize genres, but that puppetry is a major and important element.
