	Perlin noise is an [[Expression]] that takes in two values, an X and Y position, and returns a single value between 0 and 1. The value returned by Perlin noise is a psuedo-random value and can form pleasingly random yet uniformly distributed patterns when viewed alongside neighboring values.

			== What do I use this for? ==
			This is useful when you want something to feel random, but to change smoothly through space. For example, you could generate random terrain by using the X and Y of the card space as inputs, and assigning the Perlin output to the height of the hills at that location.

Perlin noise is an expression that takes in two values, an X and Y position, and returns a single value between 0 and 1. The value returned by Perlin noise is a psuedo-random value and can form pleasingly random yet uniformly distributed patterns when viewed alongside neighboring values. Perlin noise can be used to create natural movement patterns or for generating realistic terrain.
