Rob Clement emailed me: “I’ve been a frequent visitor after I had mighty Optical Illusions put on my Google homepage, and I love the site! After I saw the Canadian flag and American flag afterimages, I figured I’d try to do one myself. I just used a simple image creating/editing software that had an “invert colors” function and it took about two minutes.” This cool afterimage gave me an idea! Why don’t all of you try and make afterimage of your country’s flag. Then you can mail it to me, and I’ll give my best to publish them on Mighty Illusions! P.S. To get best effect from these afterimages, open them full size, stare at the center dot for 60 seconds, and then look at the white surface (blank piece of paper). If you start blinking, this should even make the effect stronger!
