When I got the brief, I immediately thought of using thermochromic ink for an awareness campaign about global warming. I thought of a campaign that would need the viewer to interact with, same way you would want people to interact with your cause. It is up to them to make a difference. and When they blow on the thumb print, they would see that it is because of them the human race will instinct. and the next level would be adding the flexinol to reveal the message or a slogan about the cause.
