Below you can see anamorphic images of impossible Christmas tree, impossible trident and many other anamporphic images of impossible figures. To the left are photos with reflections of anamorphic images in cylindric mirror. To the left are original anamorphic images. You can print these images and use bent mirror (or twisted foil) to see, how distorted images transform into straight in mirror.
