7 Spheres is a card game about seven spheres that constitute our environment: hydrosphere, cryosphere, biosphere, atmosphere, lithosphere, magnetosphere, and technosphere. There are six cards in each sphere representing relevant scientific disciplines: climatology in ‘atmosphere’, ‘volcanology’ in lithosphere, and so on. Participants play by exchanging cards with each other until one of them collects all six cards in a category. I designed the cards and the packaging, and drew illustrations for all the professions. 7 Spheres is being published by Maintenant, a non-profit organisation that focuses on raising awareness of environmental issues and promotes evidence-based policies and sustainable development.
