Play is a state of mind in which a voluntary activity, often governed by constraints, brings a subject into interaction with a fictitious environment. It invites to a field of exploration completely isolated from the context of everyday life. This year's theme therefore offers a paradoxical field of study where perspectives are renewed. The game offers an enclosed space of creation, without limits other than those imperiously imposed. In design, play is the exploration of awareness of limits and the ability to invent and innovate within them. How can interaction with them become a motor for creativity? Does the imagination have to be governed by borders to be propelled? The theme of this year is therefore part of a goal of framing intellectual practice, strength, reflexes, performance or sometimes even chance and offers a space where interdisciplinary collaboration is encouraged, and the abandonment of restriction in a state of freedom is favored. The possible is for the man who thinks it. This is where there is play in man.
