I did a short presentation about line perception at MU gallery for an evening focusing on bioart. My presentation relates to the artwork 'A simple line' by Jalila Essaïdi (http://jalilaessaidi.com/a-simple-line/) -------------------------------------------------------------- Matter of Art? Bio art is in full motion. It's one of the most dynamic artforms of the moment. There's a debate going on not just about the artistic qualities of the work, but also the technological, scientific and ethical questions that are being raised by it. During Matter of Art? we search for answers to these philosophical questions about bio art. Artists Jalila Essaïdi and Arne Hendriks Philosopher Laurens Landeweerd Neuroscientist Barbara Nordhjem and poet/philosopher Esther Porcelijn. Moderator: Joost Ramaer. In cooperation with BioArt Laboratories
