Optical Illusions – Series 1

by Angelos on April 26, 2009

Fullfiling the promise, we bring you the weekly dose of amazing Optical Illusion. This week we have video illusions as well.

Moving Cogs:

Appears to be a sort of perpetual motion which is actually no the case, this illusion is creation of Mr. Shebzukhov from Moscow, Russia.

Scintillation Grid:

It comes with different names, but Scintillation Grid is probably the right name. Thanks to Elke Lingelbach of the Institut fur Augenoptik Aalen in Germany, this optical illusion is available to us. Illusion: Just count the number of black points!

The Amazing Dots:

This illusion is designed by Jeremy L. Hinton of Bristol, UK. What is the point? Just concentrate on the mark ‘X’ and you will see start seeing a green dot rotating instead of pink and then these pink dots will disappear and only green rotating dot will remain.

The science behind it  is ‘Negative Retinal Afterimage’ or after image effect.

If you are still not satisfied and want to add some extra crisp to the above illusion, check this link.

Dragon Illusion:

Getting millions of hits, this is the most wonderful illusion you will come across. Put it on a table and move around it, you see the head of the dragon move across.

Theory is that on viewing a solid object, brain figures out how the object we are looking at will behave. But dragon gives us wrong impression or to our brain. The thing is shape of it, we misinterpret it by assuming that nose is pointed towards us but actually the head of the dragon is concave.

Here is the video for you:

If you want to make your own Dragon Illusion ,watc this tutorial video:

Square:

The letter ‘X’ seems to be made of different shades of colur actually it is not. It is made of single colur and can you guess which colur is that?

Natural Hallucinogen:

Watch the video, keep staring at the center and when instructed look sideways……

Tell us what saw by commenting in the comment section.

Pin Wheel Illusion:

Everything is given in the video, just play it:

Cafe Wall Illusion:

Appearing to be a chess board like, this classical illusion was first observed by Dr. Richard Gregory.

So is it what you thought: Parallel horizontal lines appears to bend.

Watermelons Illusion:

Not much of an illusion but still an illusion.

Color Perception:

This is the best example of how our perception of color changes by the colors surrounding it. It becomes impossible to differentiate between two identical colors if placed on different backgrounds.

Mona Lisa Illusion:

Two most famous paintings in the world placed up side down. Can you tell the difference?

If you spin the image right way up, you find that one of Mona Lisa looks ghastly. The reason is that your mind is not used to looking pitures up side down, thats why it could not diffrentiate between two pictures.

Motion Induced Blindness:

Similar to Amazing Dots Illusion, the rotation square behind the dots do all the trick. Focus on the pulsating circle in the center and rest of the circles disappear, in reality they are always present. Watch the video:
