Greetings!

I don't get to this section of the Café very often, and I'm not exactly sure what terms to search for. Maybe some of you can help?

I need to put together a few exercises / examples on how two people can look at the same situation, picture, or event and get two entirely different ideas of what is going on. Two versions of reality if you will.

Some examples I am thinking of are the pictures that can be either a frog or a horse, an old maid or a beautiful woman, etc. Those are a bit overused though and I need more ideas. Puzzles like the nine dots connected by four straight lines are also good for what I am trying to put together.

This is for a project for a my "day job" so any help would or advise on where to look would be great.

Sourcing is important so I can get permission to use materials.


Thanks and Best
Jim

There are some nice black and white images which look almost random till you "see" the image. Should be available via google on "perception image"

Thanks! Some of those are perfect.

I recently bought a book called "Incredible Visual Illusions" by Al Seckel.
ISBN 1-84193-197-7 in a 'Bargain Book' shop in the UK for only £5. (Standard UK price is £16 say $25)This book was published in 2006 by Arcturus.

This book has many of these types of illusions. Good book.

Yes, the Seckel book is great...and easily found in the bargain section
of Borders in the U.S.

My favorite is the Rubik's cube illusion. It's a color version
of Edward H Adelson's "checkerboard illusion." Most won't believe it...
so you should make on overlay that covers up everything EXCEPT for the
brown and "orange" center squares.

I remember the magic eye illusions. There are actually two ways to see each image, but what mind blowers they are.
