Spirals are curves that start from a center point and get further and further away as they circle around that point. They can be found in pinecones, pineapples and hurricanes. A logarithmic spiral is a special type of spiral where the distance between each turn of the spiral is progressively larger than the one before it, as in a nautilus shell.
