I was thinking about a similar topic to this the other day 'Blood Donation' and how a lot of people including myself don't even think about going and giving blood. This put my creative hat on and how I would go about connecting with people like me and encouraging them to go and do it.
Then I came across this, a corporate identity designed for an organ donation initiative created by DDB an advertising agency in Dubai. I think it works as a simple, well executed logo that strikes an emotional chord and subtly prompts people to open up to the idea. When you pledge an organ, you gift someone a new life.
