Wonderbra ad based on pure illusion

Yves Roumazeilles — Wed, 07 Apr 2010 13:17:50 +0000

This ad for the generosity of a woman bra brand (try repeating this quickly!) is based upon a well-known optical illusion. Will men fall for this one?

The dots make the disc

The rock band Soulwax created an album with a nice optical illusion for its cover. You will have a move and squint your eyes a little to fully perceive the effect.

Sun and shadows

Yves Roumazeilles — Wed, 13 Aug 2008 11:45:38 +0000

Where are the shadows? Where is the sun? This simple optical illusion could let you think that MC Escher did not survived to 2008.

Is it me? Is it you?

Do you see me?

I see you.

Slanted life

Look closely. The word LIFE is not as slanted as you’d think at first.

I love Paris illusion

Yves Roumazeilles — Wed, 16 Jul 2008 11:48:19 +0000

If you read “I love Paris in the springtime”, read again.

Teach or Learn? Simply the illusion of a difference

Yves Roumazeilles — Wed, 09 Jul 2008 11:45:15 +0000

On the one side “Teach”, on the other “Learn”. Is it all simply an illusion? Ask teachers and students.

No sex, no eyes

Will you be able to read the text? Maybe you do not have perfectly good eyes and you should blink a little.

Astronomical optical illusion

V838 Monoceroti Expansion (Hubble)

It wasn’t anything interesting until it happened but the star V838 Monoceroti, which had simply sat in obscurity, flared up in 2002 to become 600,000 more luminous than our own Sun. It didn’t take long for the star to fade back into the darkness but the Hubble Space Telescope managed to get quite a few pictures of it during its active phase.

In this series of images you can see how the star’s outer layers were first expelled and then cut away by the powerful radiation from the star. The event was made even more interesting by the fact that a “light echo” was seen. During the expansion the object appeared to expand faster than the speed of light – the effect was however merely an astronomical optical illusion.

iluzii optice (optical illusions)

Let’s forget optical illusions for a moment. I’d like to dream. But illusions come back immediately, thanks to Eugen Erhan.

Water + fluo + strobo = optical illusions

Yves Roumazeilles — Wed, 04 Jun 2008 19:13:29 +0000

Put some fluorescent dye in water, let water droplets go and synchronize a stroboscopic light. You can get anyhting you want and it looks like magic.

Black and white or Color (video illusion)

Yves Roumazeilles — Wed, 28 May 2008 18:59:47 +0000

One very cool optical illusion of a fade to black… and white.

And there’s another one very similar but with a different image: a waterfall.

MC Escher in video

Yves Roumazeilles — Wed, 21 May 2008 20:41:56 +0000

Graphic artist and painter MC Escher produced a few very interesting paintings and engravings. But today, I give you the opportunity to see it differently. Bring on the video!

Droste effect

Yves Roumazeilles — Wed, 14 May 2008 20:32:58 +0000

In the year 1956, “the Dutch graphic artist M.C. Escher made an unusual lithograph with the title ‘Print Gallery’. It shows a young man viewing a print in an exhibition gallery. Amongst the buildings depicted on the print, he sees paradoxically the very same gallery that he is standing in.”

The term was coined by the poet and columnist Nico Scheepmaker at the end of the 1970s. It is named after Droste, a Dutch brand of cocoa, whose box has a picture of a nurse carrying a serving tray with a cup of hot chocolate and a box of the same brand of cocoa.

You will find the following image and much more at AlgebraOfLife.

Straight lines are actually really parallels.

It’s your brain trying to convince you they’re not.

Lego optical illusion

It took all the art of bbzippo, some Lego bricks and some Photoshop editing, too.
