In our science communication project Adopt a Polyhedron we aim to involve a general audience to consecutively realize all combinatorial types of convex polyhedra in a collaborative effort. The participants adopt a polyhedron, give it a name and make a model of it. Thus, one by one the abstract geometrical description of all polyhedra becomes concrete. Similar to the concept of Citizen Science we call this collaborative process Citizen Art. In the workshop each participant receives their own unique polyhedron in the form of a number and a paper template. It can be formally adopted on our website. Then the participants make an individual model of the polyhedron from a material of their choice. We bring a variety of materials. The finished models will be exhibited in the venue and pictures can be uploaded to the website in order to prove that another polyhedron has found its way into being realized. The website is available under poly.mathematik.de.
