Coming from a background where there was a lot of martial arts in my life, I really came to admire movement in it and there are some specific movements that I believe really show the greatness of what humans can learn and do. If you were to ask a tiger twenty thousand years ago to do what the tiger does today  it will probably not be that hard, but if you ask a human twenty thousand years ago to do a samurai move or go skydiving it will not be that easy to convince them.

Here is a move that is done with the samurai sword which passes by the opponent twice for reassurance. It is too quick that you might not even see it move so I wanted to show every point along where the sword is moving and try 3d printing it. Then I wanted to make it geometric and have the collision points show some sort of explosion happening at them. It did not print exactly as I wanted it to but it came out well.
