Optical Illusion - rotating points of light

OPTICAL ILLUSION
These points seem to change colour and orbit the centre. But, focus on a single point and you will find that there is no change of colour or rotation.

Click on the image, if you can't see the animation.

I don't see the color change (too many years looking at stereograms) but I suspect that just as with CMYK halftone photos it is the proximity of one color next to another color that mentally creates a third color.

I can't see any colour change either. On the same theme here's a really good optical illusion. It's created rotating a solid object under a strobe light. The effects are fantastic.

You mean no-one can see the animation rotating anti-clockwise?!
WOW!

I see the animation rotating, Rik.

I think it's the changing colour description that's throwing people.
