Pappas Chain Ring: Not Rotating Correctly. Anyone Help?

[Boleeman]

Animated Pappas Chain

Hi All
I tried making an animated Pappas Chain.
It renders OK, but I cannot seem to get the animated rotation working correctly.

The Lazarus  program uses BGRACanvas2D to do the Rotation and Translation of the circles.

What I wanted to achieve was for the rings of red circles to rotate in alternate directions but with the white circles and blue circle stationary
(as shown in the attached animated gif, click on it to see it animating)

Not sure if anyone can help out , but I thought I would ask just in case someone knows how to solve the problem.
