Where nothing is as it seems.

Even though the majority of the optical illusions here are already popular, I have enhanced many of them with the use of animation. Also, a few of the optical illusions on display I've actually made myself :) The "rotating dot whirlpool", "Vision distorter" and to a large extent - the "Multi-cube" have been created by myself. For more fabulous optical illusions like these, visit the excellent site www.eyetricks.com. Alternatively, you might like to see 3D stereo pictures at the Skytopia 3D page
At first, there doesn't seem anything unusual about this picture. I mean, it's just a bunch of diagonal lines and a slightly distorted sqaure in the middle - right? Wrong - believe it or not, the lines that make up the darkened square in the middle are actually perfectly straight. In fact it /is/ a perfect square. See for yourself by loading the picture into your favourite art package.







Wow! Try staring at this for more than 5 seconds
without going crazy. Then try following it round! =)

Tri-curve

Each of the 3 curves shown below are sections of the circle.
Which would form the largest circle though?
Answer at the bottom of the page.




Skewed lines

All these tracks look as though they've come from a broken down railway track, but in actual fact, they are perfectly parallel! To prove they really are parallel, watch the small 'hairs' gradually disappear. You will see the lines as how you would expect them to be.





What does this simple green signpost say?
Guess again. Look at the bottom for the answer.

Multi Cube

Now this is very clever, even for those who think they know what's going on here. Take a look at the diagram - how many cubes can you see? You can give 1 or 2 answers, but you are not allowed to count 'overlapping' cubes as part of any one total. As soon as you think you know the answer/s, click the picture and be amazed.



What line is longer;
from a to b, or from b to c?


Amazingly, they're both the same length. This is the most extreme example I have found that distorts perception of length.
Which semicircle is brighter - the left or the right half?
Can you see dark blotches on the white 'junctions' in between the corners of these black squares?

A cool escher type shape to get you all confused.


Vision distorter
I've saved the best 'til last. Click on the left picture for a series of animations that distort the very world around you! There are anims to make everything shrink, grow, stretch, and a mix of these! You won't believe it 'til you see it.
There's certainly something very ambiguous about
which way this is meant be up.


















ANSWERS
Tri-curve: They're all the same size
Sign says "I love paris in the /the/ springtime". The word "the" is repeated.
