I've Discovered an Optical Illusion!

Grapefruitologist · Sat 18/02/2006 23:20:02

I was just playing with a paint program, and drew something, and discovered what seems to me like an optical illusion.

What do you see in this picture?

Domino · Sat 18/02/2006 23:23:20

I see a tiny picture, and i can't see anything.

Don't read this, it'll flavour your opinion of the image.

Spoiler

I see a black square, until I highlight the image, then the square contains an orange something. Its odd, I'll grant you that.

Now look at this:

Same picture, with a different background.

Not to be rude, but I don't think I'd call "oh, the brown blob is somewhat harder to make out on the white background" an optical illusion. It's roughly on the same level of bafflement as "oh, I can't read the small text on that poster over there if I take my glasses off".

Fuzzpilz, try to put it in a paint program and use the magnifier glass, and then change the background from white to black... it's alot weirder.

It's not very spectacular... But check this out http://www.michaelbach.de/ot/ Ã,Â

No. No, it's not. I recommend you investigate vict0r's link for some illusions that deserve the term (and an annoying bit of javascript on the list page, but there's worse).

I've already seen that. It's weird.

This site is awesome.
But how do I know he didn't just code all these neat effects? :p

Modernist painters was playing with the same thing about 100 years ago (or so).

Apart from that, I'd love to see optical illusions used in Adventure games. Backgrounds in the style of M.C. Escher anyone?

I think "optical illusion" would only really refer to things that exploit the way visual information is transmitted to and processed by the human brain, as opposed to art work that merely does things impossible in 3 dimensional space.

Grapefruitologist · Sun 19/02/2006 04:06:45

I know, I didn't really "discover" it, I just never knew that could happen before, and it surprised me.

I was thinking about that, particularly Magic Eye illusions (anybody ever saw those?) but I read about how they did it and couldn't possibly figure it out...

Microsoft Escher? Multiple Sclerosis Escher? Mississippi Escher? Master of Science Escher?

You can look up optical illusions on wikipedia, and scroll down to paradox illusions (under cognitive illusions) to see how Escher would fit in.

@Erenan: Sorry about confusing you, I've corrected the original post

Vict0r I tried your site but it's weird because it keeps moving when I move the mouse over some of the images!

F**king annoying so I closed it

I didn't really know what I was looking at or for in yours, Grapefruitologist... I thought I was seeing a slightly lighter box around the dark box but then you proved that one of those actually existed in the image

Anyway I made an optical illusion a bit like Grapes, tho

It can either look like a small wigwam or three propped up sticks!
But if you turn it on its side it becomes the prophet Mohammed!

I saw the orange blob the entire time :/ I have my gfx cards digital vibrance on max.
