Quinn Norton has posted the slides from her remarkable Body Hacking talk at the O'Reilly Emerging Tech conference. Quinn went well beyond modern primitivism and piercings and delved into the social mores of self-improvement through surgery and chemicals, the creation of new senses and new "super-powers." Fascinating stuff, grounded in what's going on in the world right now.
