The deformations of thin elastic objects are familiar from everyday life, from a piece of paper or clothes crumpling, to vibrations of bridges and other structures. A guiding principle of such deformations is that the material chooses to bend, rather than change its length, whenever possible. I will describe some of the consequences of this desire to avoid stretching, including the geometrical rigidification of pizza slices. I will also talk about some of the new insights gained recently from studying the wrinkling of `ultra-thin' elastic objects. Finally, I will talk about how fast these deformations happen, and some of the intricacies suggested by the Venus flytrap.
