Mathematical informational posters for my Point Line Plane online shop. These are part of a developing line of posters and booklets that make abstract mathematical concepts understandable and pleasurable by showcasing the beauty of geometry. Did you know that three of the five Platonic solids have iterations through the higher dimensions all the way to infinity? A special thanks to the contributions of mathematician H.S.M. Coxeter, whose invaluable book Regular Polytopes helped me with the data and to Coxeter's neverending appreciation for visualizing mathematics through the elegance of geometry.
