@ClaimedInfinity : Finding algorithms for patterns on the grid requires some thought, but it is not terribly difficult, especially for square grids. Try drawing it out on graph paper or in excel first. Remember that for square grids, adjacent tiles are index +/- 1 for right and left tiles and -/+ GridSizeX for tiles above and below. Because of this, Index % GridSizeX gives you the column and Index / GridSizeX gives you the row of an index. Keep this in mind, and remember to add checks to prevent the pattern from going outside the grid, and you will be able to create many different patterns with just a moderate amount of work.
