Dave 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?”
