Each of the images shown above is a distortion of the first. How do you think each was made from the original? What properties have been retained, and what given up? In particular, did any of these transformations preserve angles? Area? Distances?
Exotic transformations such as these can lead to some amazing symmetries-- some of which have barely been explored. But for now we focus on isometries, transformations of the plane that leave size and shape unchanged.
