This is a puzzle-toy, which consist of different parts of human heart. Each part of this toy is marked by special letter from DNA combination GATC and simulate natural view of human organ. It is for curious people, such as children or adults. The idea is to show, how scientific games could create the difference. Actually it is not games, cause with the help of Genetic Engineering we could grow new organs or change their structure. I designed the toy it self and also packaging with instruction and stickers.
