The Thatcher Illusion
 

cool, work safe optical illusion

LoTs more where that came from.

I actually spotted the differences before I flipped the images. I'm weird that way.

I want the eyes that follow your cursor across the screen :D

I was just reading about the fact that if you take a concave mold of a face, (e.g., the busts in Haunted Mansion that follow you) and slowly rotate it, it'll look like it's rotating in the opposite direction. Then, as the front of the mask comes into view, looking like it's rotating in the correct direction, it will look like the inverse one is "eating" the other one. I want to see that.

This one is really cool!

I came here expecting to see Margaret Thatcher turn into two vases. I leave disappointed.

I can't get that one to work for me.

On the Thatcher one I noticed immediately that the pictures were different and that the facial features on the right were flipped vertically. What I found interesting is that upside down I didn't recognize just how repugnant she looked (overall she still looked mostly fine). That's the "illusion" I took from it.

Here's a digital demonstration of the rotating mask.

Ditto.

I noticed they were different, but I thought the one on the right was just "older", not inverted. And yes, after rotating them over, the flipped features were quite frightening! Thatcher Zombie of the living dead, anyone?

Dude! :snap:
