Imagine a city in which there were only children. But children are not simple, and behave like adults. Solving some serious problems: what to be and how to produce their own food. Once at the park, the child gets two things – a bracelet that identifies its location, and several kidzo – a small amount of local money. Children have about 90 professions, issue uniforms and sent for further training. For example, to become a local taxi driver or a civilian pilot, to get right, but in order to work in the bank – to be able to count to at least fifty. These kidzo anything is missing, what is the main idea of the park – to be entertained, to be earned. The child chooses who wants to become.
