Top 10 Optical Illusions
This is a list of my 10 all time favourite optical illusions. I hope you find them as fascinating as I do!
Update: DK released this great optical illusions book in September 2012, take a look - Optical Illusions
Stare at the white dot in the centre of the red circle, and whilst continuing to do so move your head forward and backwards. For the best effect you should stare at it for 2 minutes. You will see a ring of super bright cyan appear around the red circle, and the clever part… this is a colour monitor can not actually produce!
Unbelievable tile shades
In this illusion tile A & B are exactly the same colour. I know you won’t believe me, so copy it into Microsoft paint and see for yourself… Cut out an area of Tile A and move it down over tile B, or vice versa, then Voila... told you so!
3D Dragon Illusion
This is my personal favourite, the Gathering for Gardner 3D dragon. I
currently have one spicing up my office, although I’m sure people are wondering
what I’m doing bobbing my head around like a lunatic whilst staring at a paper
dragon! Basically it tricks the brain in a way I won’t attempt to explain, but
the end result is that the dragons head follows your around the room. Insane!
You need to print this out to try it... you can download the template file for printing here: http://www.grand-illusions.com/opticalillusions/dragon_illusion/
This is one of the better rotating circle illusions. I’ve seen this adorned on many a poster, proving it is indeed a stationary image. It can really make you feel dizzy if you stare at it for too long, so be careful!
As you look around this image, you will see black dots flashing in the white circles. Well, the flashing black dots are being created by your brain!
Stare at the four dots in the centre of the image for 1 minute, then look away at something white or bright, like a sheet of paper or an open window, then your religious vision will appear.
You may not have considered this an optical illusion, but of course it is... at least for some people. You should see 58, 18, E, and 17 as they are indeed there. If you don’t see all of these though then you are colour blind!
The letter F
Finished files are the result
of years of scientific study
combined with the experience
How many letter F’s do your count in the sentence above? Quickly count through the scroll to the bottom of my Hub for the answer!
Square from nowhere
Rearranging the shapes above to make a new triangle breeds a single empty square out of thin air. Where did it come from? This has been worked out using fairly simple Maths, but I still don’t get it myself!
Real drawings of impossible situations
These are always cool to look at, a situation that would be impossible in the real world which can be created on paper with relative ease. Baffling!
What your favourite?
What is your favourite illusion?
If you are wondering the answer to the number of F’s in the sentence, the answer is 6! A lot of people only get 3 at first. Interestingly (to me anyway), I have found that children, or adults with dyslexia tend to find all 6 straight away.
