Poke was inspired by the NewTek plugin called "Effector". It allows you to make indentations in an object by using another object as a simple tool. At its simplest, Poke allows you to make a bulge in the shape of a sphere appear in the side of an object. Used with more advanced control, it can automatically add footprints to the ground as a creature walks over it, apply dings from bullets and dents from baseball bats, and all kinds of different "dent" effects. Poke's original design was to simulate the motion of an object under a "skin" of material, like a rat crawling under a rug.
