This video presents two nuts with openings facing in different direction.  A single pencil is then placed through both of the holes simultaneously in a manner that certainly looks to be impossible.

The video then goes on to reveal exactly how this illusion is performed.  But even knowing the secret to the construction of these crazy nuts does not prevent your brain from perceiving them to be crazy once they are rotated back into place.

The Lilac Chaser is a visual illusion that consists of multiple optical effects – similar to the choice between a galaxy watch vs active 2.  If you stare directly at the plus symbol (+) in the center of the image, you will notice that the purple discs will slowly disappear.  You should also notice that a single green disc rotating around in a circle will then appear.  This is caused by an afterimage effect.

This illusion was discovered by Jeremy Hinton around 2005.  He stumbled upon the illusion while researching visual motion stimuli.

Colombian artist Cesar Del Valle draws realistic images using a pencil and paper.  Presented below is his drawing called “Retratos III 7” in which a man struggles to hold up the paper over his head as it appears to be crumpling on him.  It is almost as if he is doing everything in his power to stop from becoming a paper ball thrown into a waste basket.

More of his incredible works can be viewed by visiting his blog.

Presented below are three sport utility vehicles parked in a row.  Which one is the biggest?

Would you believe that all three of these are identical and exactly the same size?  Perhaps you’ll want to measure them with something to find out for yourself.

Rex Whistler was a British artist and illustrator who among other things designed a series of faces that could be inverted to reveal an entirely new face.  In the example below, an officer of some sort is presented on the left wearing a hat with a badge on it, a collar with a series of letters and numbers and a frown.  When inverted (see the image on the right), the hat becomes a man’s mouth open with excitement and the collar becomes a hat with the inverted numbers and letters on it.

Sadly, Rex was killed in 1944 while in combat during World War II.  He was only 39 years old.  Two additional examples of Rex’s inverted faces can be found after the jump.

Jos de Mey was a Flemish-Belgian painter known for his paintings that frequently included impossible objects.  In the painting below, three owls perch on a tower that would not be possible in the real world.  Fortunately for us, we can escape the real world any time we want by diving into one of Jos de Mey’s paintings.

Brusspup creates very interesting optical illusion videos that he uploads to his YouTube channel.  You may recall the incredible portrait that he made from push pins posted two weeks ago.  Here, he has created the illusion of a chair sitting in the middle of a room when no chair actually exists.

Some behind the scenes footage showing how this illusion was constructed can be seen after the jump. Read More…
