    Default 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.

    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!

    There are three arms to the animation.
    And if you look at one of the three arms of the animation, and as that part rotates anti-clockwise, it will change colour.

    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.
