Another cool Illusion provided by Grand-Illusions. This is the idea of the two sides of human character. Have a look at the picture below. On the left is Mr. Hyde, and on the right is Dr. Jekyll.
Now, back away from your computer screen. This effect will work at different distances for different people, but you should see the two characters swap over…! As you come closer to the screen again, they revert to their original characters. Spooky or what! This image was created by Phillippe G. Schyns and Aude Oliva of the Univ. of Glasgow. It proves that we may not be seeing what’s actually there, all the time…
As optical illusions go, we think this is pretty impressive. A short explanation goes something like this. When we look at an object, we can normally see both fine detail and coarse detail. However when we are close, the fine detail will dominate, and when we are further away, we lose the fine detail, and see more of the coarse detail.
Both of the faces you see above are hybrids – each face is actually a combination of two faces. The left hand face shows an angry man in fine detail, but within the picture there is also coarse detail of the calm face. Move away, and you lose the fine (angry) detail, and just see the coarse (calm) detail.
The right hand face shows the calm face in fine detail, and the angry face in coarse detail.

View from a side angle and it seems to work for me.
if u have bad eyes and/or glasses (like me T-T) even if ur like 2 feet away, just take ur glasses off and they’ll switch
if you are able to cross your eyes and then move back and forth to computer you will see the change
funky.
this didn’t work at all for me… i saw no change
didn’t work until I removed my glasses
i like these ones!!!!!
its your blind spot… dont you listen in school?? from far away, your eyes cant take it and its because your eyes take in every image up-side down. now thats a big DUAH!!!
mr.hyde is freaky
whoa! hecka freaky!!!
Up close Jeckell looks like a girl……
i crosed my eyes and it looked perty creepy
…=^.^=
this is 2 cool
GreenDayGirl…I hope to dear god you’re joking…
that illusion is pretty cool, it also works if you just squint
also, this whole fine/coarse detail thing applies to pixellated pictures, if you look at a pixellated picture from far away or squint at it, it’ll be more recognisable
does not work if u squint. least not for me. but that is just creepy, specially since its near halloween…
The 2. face is looking more evil when you`re moving back .. I´ll have nightmares …
its funny this worked with me just taking my glasses off… damn i dont think thats such a good sign for my eye sight
this is the coolest one ive seen!!!
Dr. jekyl looks like a woman.

Blur your eyes and you won’t have to get up and back away from the computer.

Awesome illusion! i was scared to try it at first but when i moved to the side and took my glasses off it worked really good that is pretty cool!
HOLY CRAP! That is pretty freaky!
But then, I do have glasses.
Creepy.
It wasn’t working for me :(
and i was like a couple of metres back lol
till i sat back down and squinted ^_^
i had to move back about 6 feet (end of the room) and it still didnt work very well, and contrary to what other people have said, squinting didnt work either. maybe its just me.
like loser, i used the stereograph technique, and re-focused my eyes to bring the two pics together to create a VERY creepy 3d image. niiiiiice!
i can actually get them to switch without moving anywhere!
I have myopia, so I can switch views
by just removing my glasses.
It doesn’t work for me no matter how far back I am, but when I blur my vision (Like when people take their glasses off; I can force my eyes to do that) it works
It wasn’t working when i backed away and came closer, they both stayed in the same spot. However I had my glasses on. So I Took Them off and they switched when i backed away. I thought that was weird
