Pipeline #12

The only way to deal with an unfree world is to become so absolutely free that your very existence is an act of rebellion.
[Albert Camus]

I imagined a pipeline that runs within the limits of a three-dimensional cube. Each segment takes an arbitrary direction from time to time, careful not to cross the limits and not to occupy non-free spaces.
It can happen, quite rarely, that the pipeline has no more spaces available... and then the iteration stops, giving rise to a relatively simple structure.
You can follow the pipeline path by interactively manipulating the point of view.
