Stereographic projection cakes


Crystallographers in the Dept. of Crystallography, Faculty of Chemistry, A. Mickiewicz U. in Poznan, Poland, periodically hold parties (a 'special seminar' series), celebrated with a 'crystallographic cake'. Test your knowledge of crystallography and identify the point group and form represented in a stereographic projection on this delicious cake made by Agnieszka Paul!
