Hello! This is a pen animation where you see balls oscillating along their line paths but they seem to go in a circle, yes it is not a rotating circle it is balls oscillating which appears to go in a circle which is weird. If you don't believe me focus on an individual ball, you will notice it is oscillating along its line! You can change the number of balls, the size, and the speed by adjusting the variables. To change the direction you just need to click! Enjoy this satisfying animation!
