This is definitely one of the best-known optical illusions  of all times! What do you see at first glance - an old woman or a young miss? They are both there!

This is one of classic optical illusions - it is called dancing elephant. Try to count the number of his legs (by Roger Shepard).

This one is interesting. Children will probably see a group of playing dolphins. But adults see usually something else. It's called Message of Love from the Dolphins (by Sandro Del-Prete).

Stare at the dot in the center of the circle and then move your head closer to it. Neat!

Which central circle is bigger? The left one or the right one? Are you sure?

Are the diagonal lines parallel?
