This model is a progression from a basic paper tessellation of a molecule. Unlike most tessellations, it is folded very slighthly, without any overlapping. Its shape, being as far removed as possible from the classic rectangle, creates a mesmerizing vision of shifting squares, giving rise to it’s name. This model is created by four diagonal lines that emerge from the central square. It could not be any simpler, and yet the effect is quite the opposite.
