Spinning Fan IllusionDave Beeson spotted this funny gag on the the BBC homepage. I noticed that many good illusions come from people spotting them on BBC. Like for example Marina Apollonio’s installation and BBC’s optical illusions test. After you browsed those, you should try scrolling this page up and down, and you will see interesting effect that makes the fan near the girl spin! Yes that’s right, this is because of scintillating effect. This is what Dave wrote: “Hi, heres an optical illusion I just spotted on the BBC news website, it was an article about redheads… as I scrolled the page the fan appeared to spin… try scrolling the page … good eh?”

    At first I thought this was another “Seemingly Photoshopped Illusion”. Her head doesn’t look like it belongs with her body! ;)

    I couldn’t see it either because I was using my mouse scroll button.

    But I see it now! You have to drag the scrollbar on the webpage to see this.

    You have to scroll it slowly, otherwise it doesn’t work.

    Oh i get it, its a joke for people who take themselves to seriously. Its not really an optical illusion, just to make you feel like an idoit for trying to see something.

    Don’t use your mouse: just press the cursor up and down keys alternatively very quickly instead, to make the page go up and down slightly.

Speak Your Mind

You can add some images too.
