The fourth international conference "Taboo - Transgression - Transcendence in Art & Science" will take place November 26–28, 2020, exclusively online as TTT2020 Vienna/Online, an umbilical cord between what would be and what it is. Including theoretical and art practice presentations, TTT2020 continues to focus (a) on questions about the nature of the forbidden and aesthetics of liminality as expressed in art that uses or is inspired by technology and science, and (b) on the opening of spaces for creative transformation in the merging of science and art.
