Here's another one, but this time I realise it's a concept rather than a real life campaign. It's an idea to increase blood donations to the Red Cross. It's made by a group of students in Brasil.
We all want our cause to be relevant to young people. But we can't just broadcast and expect people to tune in. We need to think long and hard about where we put our messages and think even harder about what we can give in exchange for peoples attention.
Which is why I like this one so much. It's simple. It makes the point. It will get a response.
I found it on the brilliant Adverblog, a blog well worth looking at.
