The previous version of The Swirl 2, was so complex. It contained 3D position rendering, color switching, and orbit. And the whole thing was so big that sometimes you can't see the lines and else.
So I tried to fiddle the whole thing in the center, and the rotation can be controlled by the mouse. It doesn't spin by itself, but the image shows the change when you move the mouse like mad.
The three straight lines show the axes of the stage. Red one is x-axis, green one y, and blue one z.
Enjoy the ride with the dragon groove.
