[Scratch] Vortex effect

It is a program that draws a spinning vortex.

It is this program that draws one part of the vortex. I’m just drawing while changing the thickness and orientation of the pen.

When I run this program it looks like this.

In the end, 12 vortices are drawn if the angle is changed by 30°. Furthermore, it is animated by repeating redrawing while changing the start angle of those vortices.
