My dad sent me an email forward today (which, sorry Dad… sometimes I just skip over…) :-) But, today I checked this one out with Ian, who happened to be in the office with me. These three were pretty cool!

Is It Moving… Or Not?!?
Spiral Illusion
Focus on the dots in the middle of these circles. Then see if you can “catch” one of the moving circles with your gaze. Click this picture above for a larger version. (Right-click to download.) You could even make it your desktop if you wanted to…

In and Out
Spiral Illusion
Focus on the dot in the center and move your head back and forth from the screen. Cool…

Ian’s Favorite…
Illusion
Focus on the four dots in the middle for about 30-40 seconds. Now, close your eyes, and turn towards a wall, or for me, it worked better looking at a light. You will begin to see something appear inside your eyelids. Or rather, someone. Sorta. :-)

Just a little fun to pass along. Enjoy. :-)

    I’ve done that bottem one before and it is soooo cool. In fact, it’s so cool, I’m putting it on my blog too!

    What the… I got that e-mail yesterday, too, from Jack. The old guy who used to be the security guard in college.

    Old people love optical illusions.

    Wow. Jack. That’s a blast from the past. Very nice.
