Por ser um tema quase inédito, foi importante explicar o significado dos termos tilt, bug, failure, fault, error e mistake em relação ao campo técnico e artístico da Glitch Art, à sua prática e a nossa experiência, assim como a definição do termo glitch e de seu uso como designação deste recente gênero artístico. Seguiu-se para a investigação de suas bases fundamentais, classificações, características visuais, procedimentos artísticos, relação com o passado da arte, seus artistas visuais mais expressivos e sua aplicação para além da arte digital. Para tanto, este trabalho apoiou-se, principalmente, nos pensamentos de Moradi, Manon, Temkin e Menkman nos aspectos exclusivos da Glitch Art. Por fim, de modo teórico-prático, resultou a criação da obra Decode, de minha autoria, onde se dialogou e se experienciou as teorias e os procedimentos aqui discutidos. / This research aims to verify the possibility and aesthetic potential through the use of digital error and not designed uses of technical devices and software in Glitch Art. For being an almost unheard subject, it was important to explain the meaning of tilt, bug, failure, fault, error and mistake terms in relation to the technical and artistic field of Glitch Art, its practice and our experience as well the definition of glitch term and its use as designation of this recent artistic genre. We proceed to the investigation of its fundamental basis, classifications, visual characteristics, artistic procedures, relationship with the past of art, its more expressive visual artists and its application beyond the digital art. Therefore, this research grounds on mainly thoughts of Moradi, Manon, Temkin, and Menkman in exclusive aspects of Glitch Art. Finally, with theoretical and practical way has resulted in the creation of my own work Decode, where was connected and experienced the theories and procedures discussed herein.
