An adaptation of the Maze Equation by Fabrice Neyret - See "Notes and Credits." How it works: The screen is divided into cells, and either the left fourth or the bottom fourth is colored black, determined using a cheap hash function. The cells are shaded by seeing if the range in either X or Y depending on the orientation of the cell, is within a value (Within the cell - mod function)
