Here at Optical Spy we are not all about illusions we just like unusual opticals. We also have a love of periodic tables (you might be interested in this one at our other website Deskarati) but we couldn't think how to make one that was a bit different. We eventually hit on the idea of a tetris table. Hope you you like it. Just click on it to start over.
If we start a small circle rolling around the interior of a large circle of twice its diameter and we follow a point on the small circle shown here as red dot, what pattern will it draw? Click the picture to find out.
A bit of a reversal on the old perspective illusion for you here. Hopefully this one might fool you.
The ballerina and the fence are rotating together as one rigid thing. No joints.
Nonetheless we perceive the ballerina rotating in a different direction to the fence.
This optical shows a graphic superimposed in front of a set of metalclad louvre doors. All seems fairly straight forward two circles inside a rectangle. But of course everything is not what it seems. Click on the picture to see what is going on.
