The Cyborg series started back in 2015 with the first piece (Cyborg I) being a migratory locust that got a new leg out of a safety pin after I dropped the original preparation. When I got to know about super-thin PCBs, the idea of the Butterfly came to my mind. Also, at the time I was the lucky owner of a Nokia 8800, which has a rather sophisticated sliding mechanism that requires such flex PCBs.
