Can good ol' human intelligence decipher these optical illusions? We merged design tricks with some trusty psychological secrets to give your brain - and eyes - a challenge. Can you work out what's going on?
Question 1 of 5
This is actually a completely static image. Subtle shading and highlights in the right places trick the eyes into seeing motion when there is none.

The artist drew six faces into this picture, but our brains are hardwired to recognise faces in virtually anything (a phenomenon called 'face pareidolia').

Question 3 of 8
This is an example of a 'scintillating grid illusion' designed to show flashing dots - without any actually being present. Your eye is reacting to the specific way the grey, black and white are arranged. The illusion will appear even greater in your peripheral vision.

Question 4 of 5
The colours are actually the same shade all the way through. The image isn't spinning either. It's all thanks to strategically-placed shading (the black triangles) and highlights (the white triangles).

This is an example of an 'autostereogram' which only works when your eyes are positioned a certain way. The trick is to focus your eyes behind the picture. After a while, a 3D image of two camels should form.
