 OFFSET 0,19 COMMENTS The ant starts on a completely white grid. Order of operations: turn 90 degrees, change cell color, move forward one unit. The rules governing the movement of the ant and the change of cell colors are shown in the following table: Cell color at      | Direction of   | Color the cell is start of iteration | 90-degree turn | changed to -------------------------------------------------------- white              | right          | black black              | left           | blue blue               | up             | yellow yellow             | down           | white LINKS Felix Fröhlich, Illustration of iterations 0-50 of the ant Wikipedia, Langton's ant EXAMPLE See illustration in links.
