Fun with fractals #2, Fractal Square. [Fractal Triangle #1]
Process notes. Inkscape. Six iterations. Started with inner square, moved out.
Is it fractal if the design does not repeat cleanly and eventually runs into itself?
First iteration (yellow, big) – open on four sides
Second & third iterations (green & blue) – open on three sides.
Fourth iteration (pink) – some touch the yellow square and therefore are only open on two sides
Fifth iteration (red) – many open on two sides, the rest on three sides
Sixth iteration (purple, tiny) – anywhere from zero to three sides
Hat tip again to Gement for introducing me to this rabbit hole.
Onwards!

This would make a nice, if complex, quilt pattern.
