Handout film still from Cyborg: A Documentary. Colour-blind artist Neil Harbisson is the world?s first formally-recognised cyborg. He has an antenna implanted in his head that allows him to ?hear? colour. Now Neil is on a mission to convince the world to follow him and adopt his credo: Design Yourself. Neil?s childhood friend Moon Ribas has collaborated with him on his journey. A dancer and choreographer, she has had implants in her arm and foot which allow her to perceive earthquakes from all over the planet as vibrations in her body. In Carey Born?s engaging documentary Neil and Moon confront their detractors head-on, communicating their controversial ideas about the technological future of humankind.
