Simple and amazing

Actually this is a set of poster and I just pick out one of them. All posters are amazing and original. They're simple and significant at the same time . For example ,in this poster all brains are grey and dark except one colorful brain. The contrast is clear and strong. And it expresses the emotion directly. Instead of some magnificent posters,I prefer these simple style posters which are neat and outstanding. It's hard to design a good poster ,maybe sometimes we should give up complex designs .
