Designers think positive. Way to go!
Positive Posters is a local non-profit organisation that brings designers together from around the world (in the online sense) to raise international awareness for social issues. They run an annual poster design competition which is cool, but perhaps more interestingly, they encourage designers to put their positive posters up in conspicuous places.. Its worth visiting their site to see the huge number of entries, many of which are quite wonderful. And, of course, positive. Mostly.
As a sideline, they also this year ran their first conference for graphic design students with the brilliant title Sex, Drugs, Helvetica.
What more could you want from a bunch of designers!
