Butterflies rotating clockwise

Quantos rostos há nesta árvore?

Consegue ver uma mulher deitada nesta gravura?

E neste quadro, quantas pessoas vê?

Quantos animais você vê neste quadro?

Are the lines below straight or are they curved?

Try putting a straight edge against the lines on your screen to test your conclusion.

Rotating pink dot

If your eyes follow the movement of the rotating pink dot, you will only see one color, pink. If you stare at the black + in the center, the moving dot turns to green. Now, concentrate on the black + in the center of the picture. After a short period of time, all the pink dots will slowly disappear, and you will only see a green dot rotating if you're lucky!
