Square Routes Revisited

Take a square, divide it into four smaller squares, and discard the smaller square on the top right. Do the same to each of the subsquares, dividing it into four sub-subsquares, then discarding the one on the top right. And repeat with the sub-subsquares. And the sub-sub-squares. And the sub-sub-sub-squares. And so on. The result is a fractal like this:

sq2x2_123_1

Stage 1


sq2x2_123_2

Stage 2


sq2x2_123_3

Stage 3


sq2x2_123_4

Stage 4


sq2x2_123

sq2x2_123_static

Final fractal (static)


It looks as though this procedure isn’t very fertile. But you can enrich it by rotating each of the subsquares in a different way, so that the discarded sub-subsquare is different. Here’s an example:

Stage 3


Stage 4


Stage 5


Stage 6

Here are more examples of how rotating the subsquares in different ways produces different fractals:
