Goosenecks Illusion (revisited)

[stefan]

okay, when i first came onto this forum i posted this illusion i discovered by surprise one night with a couple of friends. although i presented the illusion with an image i found on the internet i finally got around to photographing the book in which we found the illusion ... Stokes' Geology of Utah.

this image works a lot better and is worth the peek if you've alread seen it. on the following link i describe how we stumbled upon the illusion and show photos of the book.

enjoy

I can't get the inverted image to appear like a canyon, it always looks like a mesa to me.

I can't get the inverted image to appear like a canyon, it always looks like a mesa to me.

i agree. the only way i can do it, is by slowly rotating the image from right-side-up to upside-down ... then once it snaps to the mesa, all is lost for me. i figure if one did it enough to train the brain to become familiar with the upside-down image as a river, one might be able to learn to see it both ways. but i haven't bothered to try this.
