Happy Mutants is an occasional podcast of interviews with creative people. I’m Mark Frauenfelder from Boing Boing. In this episode, I interviewed Mark Williams and Sasha Robinson, designers of a new instant-on, lithium-ion battery vaporizer called The Firefly. It is an incredibly cool piece of technology.

Every detail of the Firefly has been the subject of intense obsession by Williams and Robinson. Williams said he received the best advice of his career from Steve Jobs while working at Apple who told him to “build the best thing you possibly can.” Williams took that to heart, honing his craft in positions of design leadership for over 20 years at Silicon Valley. After meeting fellow designer Robinson, the two friends became business partners in 2011, channeling their combined expertise into launching the Firefly vaporizer.
