Iron skillet meets iron fist. Some of the most striking visuals to come out of this year’s TED conference weren’t made for the stage but for the street: Jamie Oliver‘s Food Revolution truck, an 18-wheeled kitchen classroom designed pro bono by Rockwell Group, launched last week and represents just one of the outcomes of Oliver’s 2010 TED Prize wish to make kids healthier. The wish of this year’s TED Prize winner, the artist currently known as “JR,” is that people will participate in his global art project INSIDE/OUT and help paper streets with gigantic portraits of themselves. Step 1: set up photo booths that print poster size pics of conference participants–quite a surreal experience, writes Guy Horton for Good.

Discover the history and location of dead amusement parks, overgrown hospitals, forgotten hotels and creepy ghost towns.”
