While it might tout the values of wearing helmets during extreme sports and the like, DDB Canada's site for BRAINTRUST doesn't come off as preachy. Instead, a 3D brain simulates the social aftereffects of brain injury via a multitude of tests that taunt your equilibrium. Every test, including "Feelings," a multiple choice study that shows how you're unable to manage them, and "Cellphone," which confounds the mind during a round of flirtation, comes equipped with factoids that show what it's like when the brain gets rattled, no matter how small or large the injury.
Along with the tests, the site also includes links to a MySpace profile of "Brian Ingury" (get it?) as well as a series of videos showing folks engaged in sporty activities while wearing a helmet.
