@ -45,3 +45,9 @@ Eine einfache Sinus-Funktion über eine Periode in Rot.
Ein rotes Pixel läuft herum und wird dabei immer lichtschwächer &
blasser.
### `halfSineOverlap`
3 Sinus-Halbwellen in Rot/Grün/Blau, die mit unterschiedlicher
Geschwindigkeit (1x/2x/3x) über das Band laufen und bei Überlagerung
auch entsprechend die Farben mischen.
