Description Presented here is a vast gallery of many different forms of Optical Illusions. Whether these optical illusions are conveyed through fractals, photographs, architecture, art, or old fashioned pen and ink, they are bound to remind you that "seeing is not believing."

Caution!!!! Some of the optical illusions on this blog may cause dizziness or possibly epileptic seizures. The latter happens when the brain can't handle the conflicting information from your two eyes. If you start feeling unwell when using this website, immediately cover one eye with your hand and then leave the page. Do not close your eyes because that can make the attack worse.

Tesla Coil Etc...

No illusion here. This is the real deal operating at 15 kva or 15000 watts. Every now and then I have to place a non illusion post up because the name is Optical Illusions Etc... This tesla coil was created by David Riebens.

Real Impossible Construction?

This optical illusion is very well done. Can you guess the exact nature of this construction.

Hint: Not all seemingly 90 degree angles are even close to 90 degrees.

Sexy Silhouette Optical Illusion

I love good silhouettes. They are almost always ambiguous. When dealing with a silhouette the subject can be looking toward you or away from you and the lines can be drawn in to show either perspective.

Which way is this lovely girl actually facing?

Trompe l'oeil Ad

This is an ad for ramen in the causeway Bay Station in Hong Kong. I love this kind of art. I would love to see this from a angle that reveals how distorted this image needs to be to get this one perfect view.

Impossible Objects Optical Illusions

Here are a few excellently rendered impossible objects by Josh Sommers. Excellently done, thanks for allowing these via the "blog this" feature of Flickr. Josh talks about the first optical illusion presented.

"A variation on the 2 or 3 prong image, inspired by the work of Walter Wick, who managed to photograph his version using a partially reflective piece of glass and very careful lighting to create the illusion. "

Dead Paper?

Here are a couple of fascinating creations by artist Peter Callesen the first creation is a closeup of the original piece. The only material used is Acid free paper, pencil, and glue.

I love the skill and creativity of this artist. Is this skeleton breaking free of his two dimensional chains or settling in for a nice long nap.

Shadows in the Mist

Again I take you into the Etc... of Optical Illusions Etc... Not everything in this blog is an optical illusion, some of it is frightenly real.

On August 11, 1999 a mysterious black mass swarmed across the surface of the planet. This might be biological in nature if it wasn't for the fact that it moved at almost 2000 kilometers per hour. Could this be extraterrestrial in nature? Is this phenomenon proof that we are being visited from other worlds?

Explanation: Here is what the Earth looks like during a solar eclipse. The shadow of the Moon can be seen darkening part of Earth. This shadow moved across the Earth at nearly 2000 kilometers per hour. Only observers near the center of the dark circle see a total solar eclipse - others see a partial eclipse where only part of the Sun appears blocked by the Moon. This spectacular picture of the 1999 August 11 solar eclipse was one of the last ever taken from the Mir space station. The two bright spots that appear on the upper left are possibly Jupiter and Saturn, although this has yet to be proven. Mir was deorbited in a controlled re-entry in 2001

Whichever, Optical Illusion Animation

This film is the creation of Yutaka Akita. This short film has bits and pieces of many favorite illusion topics such as recursive, fractals, tessellations, and perspective. He describes this video as follows:

"This is application experiment of optical illusions commonplace in 2-D animations in 3-D spaces. The animation develops through illusions caused by concurrent different perspectives of simple lines and surfaces. It is a non-narrative film aiming to make viewers feel bizarre yet fascinated by a feeling of floating between real and unreal."

For more films from this artist go to this site. Here is a short biography he provided on his Dailymotion page.
"Born and bred in Yokohama, Japan. After a study of Byzantine art at Waseda University, surprisingly Yutaka started his career in the film industry where crazy yet creative people are working hard every night and day to make something amazing. Couple of years after, he alone went all the way to the UK to cultivate his style and techniques as an animator/director. And here he is, working on a variety of projects including promotion video for Madame V spring/summer collection 2007, James Bryan “Beautiful World” video, etc. He also worked for Johny Mourgue, one of the film director in FLYNN Productions and made a pitch for Beck’s album “Cell Phone’s Dead” TV spot. *showreel available on requests."

Fire and Water Optical Illusion

If you had a need to boil water and only had a candle and a glass, what would you do? If you were photographer Georg Pillwein you would be creative and boil the water from inside the glass.

Having the flame directly in the water has to be a very efficient way to transfer energy to the water. I only wonder why other folks didn't think of this earlier.

Optical Illusions of Smoke

The following are actual photos of smoke, true some post processing was done but everything you see in these images is photographed smoke. These are the work of Csaba Mészáros of Budapest, Hungary. I asked him permission to use the "Intimacy" image and he suggested two others. The most amazing of the three is the one below titled "Mom and Baby".

You can read a brief biography on Csaba and find out exactly how he accomplished these amazing images in the January 2007 issue of PBase magazine.

Here is a short starter explanation he gave in a comment a couple years back,
"The setup is quite simple: the smoke comes from incense sticks (made in India), they are cheap and produce a constant smoke for a long period of time (and also a pleasant scent). The light source is a fashgun from side and behind. You need a black material for the background and something to shade the direct light from the flash to the lens. Plus some patience and some trials. "

Bending Lines Optical Illusion

Here is an anomalous motion/distorted perception illusion.

The apparent motion induced by the blue spots seems to cause the red lines to bend and wave. If the whole image is in motion how could red lines not be bending with the motion?

These types of motion images confuse the eye and brain. This confusion allows the viewer to perceive motion in a static image. That's right the below image is a static image and is not animated in any way.

He has just finished his latest masterpiece as part of FestivALL Charleston 2007
“A City Becomes a Work of Art”. Julian's preliminary sketches depicted an urban theme with a skyscraper. However, the FestivALL committee suggested a drawing more in tone with the state.


The Beginning

Photographer Adam Harris


Typically his creations take about 24 hours of work to complete. Julian started his latest work at about 11am on Monday 18 June and he finished it up about 6pm on Thursday the 21st. Rick Lee was on hand for the final hours and has allowed us the honor of showing his photos here.

The following photographs were all taken by commercial photographer Rick Lee. To start with here is one of Julian Beever putting the finishing touches on this excellent work of art.

This type of art is anamorphosis, which means the image appears distorted unless it is viewed from a special angle or with a special instrument. Below is a view of the finished artwork from the back angle. Our cute little raft is now very odd and the little ledges at the edge of the pavement are now huge.

Erotic Silhouette Optical Illusion

This came to my attention via Kisrael.com. I know what some of you might be saying, I said the same thing when I first saw it. "How the heck does this classify itself as an optical illusion? For that answer you'll have to read the full article.

Ambiguous Rotation

This is very much like the Ferris Wheel optical illusion I posted previously, depending on how you look at her she will either be spinning clockwise or counter-clockwise. You don't believe that it is possible for your mind to see this image rotating any way but the way you see it now, do you?

One of the reasons that this is possible is that it is a silhouette and the very nature of a silhouette is ambiguous.

Try looking at the reflection and see if she reverses direction. I shift my focus to the side and can tell in my peripheral vision that she has changed direction, I then move my eyes back on the silhouette and walla she is rotating in the other direction.

What is even more amazing is that if you see her spinning clockwise then it is her right leg and arm that is up in the air, but if you see her spinning counter-clockwise then it is her left leg and arm that are up in the air.

My initial view of this illusion is that she is rotating counter-clockwise, but once I manage to see her spinning the opposite way it is hard to switch back. Which way does she appear to spin to you? Can you see her spin in either direction?
