There are 4 settings on the corners. The points all move in a straight line, use the bottom slider to display the lines and you will see... (Try number 13, coefficient 25 and the circle will turn the other way.) Thank you for the 100 000 views ! #circle#illusion
A big thank you to the scratch team for featuring my project and to @Poupoupidou58 for proposing it in the feature studio.
