Terrible title, but I could not think of anything better. Used for spelling a phrase where each word of the phrase is a different value of cache parameter. Different type, terrain, size or difficulty. So for instance, "Lets climb hills" where you spell "Lets" with terrain 1.0 caches, "climb" with terrain 2.0 and "hills" with terrain 3.0.
