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.

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.
Well, thank goodness, for that!Quote:

By the way, the animation was not made by me.
And the description is not mine, either.
It's just that I can see what the description says, quite clearly.
Rik, I understood what you had described and was impressed that our brains can be so simply deceived.
I thought the counter-rotation was clever.
Then when I checked that each ball has a fixed path, neat.
The addition of colour and trails was just the icing.
At that point, I thought I could do that and was happy.
