where i learned the basic method:
• Celtic Knot - 2
where i learned a bit about inner walls
• Celtic Knot - 1
I have recently developed a more sophisticated application for designing these knots; please see my other video if you are interested. The knot created in this demo, visualized with the new application can be viewed here as an image:

note, this is slightly different from the image pictured in the video, in that i closed the outer border by selecting all of the red barriers along the perimeter
