The beat seems to adapt itself to the rythm of their movements. Small robotic structures form into complex configurations, some levitate momentarily with gravity reflectors (employing the Stillman-Kohrinck principle), some quickly evolve intricate gaits and walk cycles. Some very familiar, others rotational-based, spin-walks and loop vortex propulsions, wonderfully unfamiliar to the observers. Just as suddenly, the structures break up and scatter, ready to rebuild again.
