Eye Test For Blacksmiths

[Blacksmith58]

I came across this picture and had a very strange effect when you scan your foucus slowly around to different places in the field. Do you see movement or not? Am I alone in this effect? I'm looking for a reason why this happens; any guesses???



Just scan the immage like you are viewing the suttle curve of the small of a Ladies back. Don't focus on any one spot, keep your focal point moving around the image. Can you see the effect?

I hope I'm not alone!

Its an optical delusion!

LOL, it only works if you have two eyes, like with 3D.

I should remember what these are called, we did a day worth of optical illusions in an art theory class in college. Try "optical illusion" on wikipedia. The real trick would be if someone could repousse a similar pattern on sheet copper/aluminum/steel/brass that would have the same effect ( i am not volunteering )

[Blacksmith58]

I don't know what the heck they're called but here is another one. Lets' see somebody repousse this one!

[ApprenticeMan]

Haha! Try this one! And wait until Julian Sees this one!

The science teacher across the hall from me does some of these things to our kids once in a while. Something about there are blind spots at certain places in our eye sight and our brain automatically takes the surrounding image and "fills in" the missing dot. And I would hypothesize the movement comes from your brain constantly adjusting to meet the right color and shape. Some people can actually see the dot in their regular vision. I thought the guy was full of it until he made me cover up one eye and hold a pencil out at this certain place and part of the pencil disappeared. I can't even begin to describe the steps to do this, but it worked. I accused him of tricking the kids, and like any good science teacher he sat me(the skeptical government teacher) down and proved me wrong. So for the rest of that day I had our kids were all talking about how cool the day was. I should have known better...But it was still fun. These will show up in his room tomorrow! Thank you for sharing!!!
