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 during this course, the idea of the Butterfly came to my mind. Also, I was the lucky owner of a Nokia 8800 back in the days, which has a rather sophisticated sliding mechanism that required such flex PCBs. Putting things together, now there is another Cyborg.
