The image of the poster of the 6th BMS Student Conference was created by Josué Tonelli-Cueto. It contains a glass representation of the immersion of the Klein bottle, surrounded by a Möbius band made out of camera film and on top of pieces of a Penrose aperiodic tiling of the plane. The organizers are thankful to Prof. Marta Macho-Stadler for providing and allowing to take photos of the objects in the poster.
