Facebook Application Optical Illusion Challenge

Of course, today I opened my Facebook and over around 20 applications invitations to install this particular one catched my attention so here it goes the review for the Optical Illusion Challenge. My life story with this type of mind games has always been sad because I am not to good for this kind off stuff.. or maybe I wasn´t in the past and because I had a score of 100% - Yes as you read 100% - this review is half review and half show off!! LOL.

This simple Facebook Application provides 12 optical challenges. But first things first What the heck is an optical Illusion?? . According to Wikipedia:

"An optical illusion is characterized by visually perceived images that, at least in common sense terms, are deceptive or misleading. The information gathered by the eye is processed by the brain to give a percept that does not tally with a physical measurement of the stimulus source. There are two main types of illusion: (1) physiological illusions that are the effects on the eyes and brain of excessive stimulation of a specific type - brightness, tilt, color, movement; and (2) cognitive illusions where the eye and brain make unconscious inferences.

In less words, is something that you see but is not there. So here is this Facebook application to fool us for a while with 12 different challenges where we are tested while asked to answer some things that we see that apparently seem to be really clear to our eyes but to our surprise most of times in the first try we are wrong.

So enjoy it and see how good you are perceiveing the inexistent, on what you see,

My qualification for this app is 3.0 out of 5, because It ´s interesting but after the 12 questions there´s nothing else to do with this app.

If you are looking for more complicated Illusions check this site that I found, and now is giving me a hard time specially with this one the I am linking in here, for review. Here I copy the challenge for you.
