Harbisson, whose U.K. passport shows he’s the first legally recognized cyborg, was born colorblind. He designed his antenna—which translates colors into one of 360 musical tones he’s memorized—back in 2003 with help from a cyberneticist. At first, he connected it to headphones and a laptop. Eventually, he persuaded a surgeon to drill into his skull, implant a chip, and fuse the antenna to his occipital bone.
The couple say merging technology with their bodies has created new senses. “We are transspecies,” says Ribas, whose three-year-old seismic implant vibrates at different intensities based on data from online seismographs. As with other biohackers, their claims—he says my color registers as an F sharp, for example—are difficult to verify. But their London startup, Cyborg Nest, is manufacturing DIY kits meant to bring their transhumanism closer to the mainstream.
