/* Falowanie znaku. Cały znak obraca się bez końca w jedną stronę o 72° na cykl – znak ma 5 fal,
   więc po 72° wygląda identycznie i pętli nie widać. Na to nakłada się kołysanie pierścieni
   z przesunięciem fazy (od środka na zewnątrz). Kołysanie jest wolniejsze od obrotu, więc
   żaden pierścień nie cofa się – tylko przyspiesza i zwalnia. */
