‘Helmet of Justice’ uses seven cameras to make a black box for bicyclists

Design studio Chaotic Moon is known for its work on the “Board of Awesomeness” and “Board of Imagination,” which push the humble skateboard into new territory with electric power and thought control. Its followup takes on a somewhat different problem: giving skaters and bicyclists an antidote to their vulnerable position on the road. The “Helmet of Justice,” demoed on CNN last week, was developed in response to a hit-and-run that left Chaotic Moon employee John Poindexter injured with no idea what had happened.
