Each line in the fractal follows its own unique path, while staying connected to each other. They do not cross other lines and they do respect the blank space around the edges. However, the lines need each other to form a beautiful fractal together, despite of their difference in direction, speed, and appearance.

This is also how we should live together as a society. Like the fractals, we should not cross each other’s lines and stay connected to each other. Then we can work together to reach incredibly beautiful achievements while leaving room for nature to flourish.

The fractals all start in the centre and expand outwards in a different number of branches. There are four different colour modes, but the same mode will have distinct colours each time. There are three different boundary conditions, but sometimes, the fractals do not expand far enough to reach the boundary, then it is not visible, but even more unique.
