A great new visual effect is revealing the physics of Kung Fu in all its dynamic glory. German digital artist Tobias Gremmler used motion capture of a Kung Fu practitioner moving through a typical drill. The video recreates the whirlwind of activity using myriad materials, including fabric and sticks and balls. The visualizations are inspired by the motion, speed and direction of different body parts. The swirl motion changes continuously, sometimes resembling rapidly written calligraphy or liquid swirling spirals, while at other times a human form seems to morph in and out of existence. At other times, the body appears to resemble a building structure or a precarious pile of bricks that collapses on a moment’s notice.
