Optical illusions are all the rage, from those that test your powers of observation to others that reveal how fast your brain works.

Now a deceptively simple illustration that is sweeping the web as viewers test what it says about them. So what do you see when you look at it?

Analysis by Playbuzz user TeacherQuizzes explains the personality features associated with the image, reports NZH.

If your first reaction to the picture is to think it's the back of a young girl's head, you are "optimistic and beaming with positive energy".

This is also associated with being curious and passionate about trying new things, as well as being generous.

However, seeing the girl's head isn't all positive, as it also implies impetuousness.

The quiz says: "You have a tendency to take action based on impulsive decisions."

It also advises asking for help from others: "You will develop and grow into a better person with the multiple feedback, advice and support from people around you."
