Reverse
1) Pick one point that isn’t touching the edge of the paper.
2) Draw At least four lines from the point that are not perpendicular or parallel to each other.
Lines must somehow touch each other, but not cross over each other.
3) Pick one line a draw at least one line perpendicular to it. The new line need not to be perpendicular to the surrounding lines. New lines must not overlap any other lines on page.
4) Continue to repeat step 3 with existing lines and new lines until satisfied with image.
5) Repeat steps 1-4 at another point on page if desired. New design cannot overlap existing lines.
End result.
