Candy Cane Optical Illusion

In the spirit of the holiday season, today’s optical illusion features a series of red and white candy canes.  When you look at these seven pieces of candy, do they appear to be parallel to one another or are they askew?  If you want to be certain, grab something with a straight edge and hold […]

Terror Subterra by Roger Shepard

It certainly does not appear to be true, but the two monsters shown in this illustration are identical in size.  It looks like the monster in the background is significantly larger than the one in the foreground (maybe even twice the size).  This was originally published in Roger Shepard’s book “Mind Sights” in 1990.  In […]

Concentric Circles by Akiyoshi Kitaoka

Have a look at today’s image that was created by Professor Akiyoshi Kitaoka from Ritsumeikan University in Kyoto, Japan.  We’ve posted images similar to this one in the past, but I thought that it was a pretty good representation of an old optical illusion concept.  Each of the rings are circles, even though they certainly […]

Spaceships Optical Illusion

In this new twist on an old optical illusion, two spaceships can be seen flying through a wormhole.  The spaceship in the front appears to be significantly smaller (maybe half as big?) than the one behind it.  Surprisingly, however, both spaceships are the exact same size.  The wings of the spaceship in the back are […]

Spheres Relative Size

The sphere that is placed closest to you looks to be about half the size as the sphere in the background.  Surprisingly, both spheres are exactly the same size.  If you don’t believe it, grab a ruler and measure them both to confirm. For a similar effect, be sure to revisit the SUV Illusion where […]
