I am seeking help to create a video about the #3D #geometry that links together the chains in Dynkin Diagrams in #Lie theory. Namely that a rotation by 120 degrees plus a #rotation by 120 degrees yields a reflection by 90 degrees. I appreciate #help from domain experts so I understand this better, from interested #learners to give feedback, from #animators, #artists, #programmers to present this, and from #actors to make this fun and engaging https://github.com/leios/SoME_Topics/issues/239
