World Wildlife Fund (or just WWF in short) is an organization we mentioned few times in our past. It’s an organization which protects endangered wildlife and environments, tackles climate change and promotes sustainable use of resources. But what WWF also does, it creates one hell of a memorable billboard campaigns. To raise awareness around their cause, they need their message to stand out and differentiate itself from the rest. And what could be better to promote this worthy cause than using a poster with built in game, one that traps you into the world of rainforest wildlife? Not only have I learned one interesting fact today – that rainforests only cover 7% of our planet but harbor more than 50% of the world’s species – I’ve also learned there is pile of hidden animals present in this poster below. Open the picture in full-size (by clicking on it) and see how many hidden animals you can find. Let the games begin!
