I can't see 'em, either. Never have been able to.  Tried these on the pc monitor and by printing out the one on the link that Maj sent.  Looked carefully at nose distance, moved the thing out until I could see 3 red squares, gazed until I got a headache - with and without my glasses - but could only see lots of little coloured stars.

Oh well...  I can detect the soapy taste of rancid coconut at extremely low levels, for whatever that's worth.    :yucky:

It really is just a matter of getting yours eyes in the 'wrong' place. If you are too close to the image you won't be able to do it because most people can't move their eyes further apart than parallel. Your eyes can focus to further distances, so you can physically see it, and once your brain locks on it will stick. Try looking over the top of your laptop into the distance - you should (in your peripheral vision, looking will obviously refocus your eyes!) see the stereogram go out of focus; the aim is to carry on looking 'through' the picture as if it was transparent and there was something behind it you were looking at.

Just staring at it won't get you anywhere (in fact, the trick is _not_ to look at the image but to have the image in the way while you look at something behind it).

The mushroom cave one is quite tricky to 'lock on' to.

It looks like a 3D image (reversed) of a bear (or similar)  :)

Ah! If your seeing the reverse image ie a hollowed out bear, then you are focusing on a point between the screen and your eyes. If you focus on a point beyond the screen the image will appear as a solid object, in this case the bear.

For those that wish to see the reverse image. A good way is to put your finger near your eyes and focus on it, then slowly move it away towards the screen just below the image but keep your finger in sharp focus. At one sweet spot the image behind comes into focus. At this point move your finger away and your eyes should lock into the reverse image.

Also once you get good at this sort of thing (and the simple stereograms where there are two very similar pictures next to each other) you get really good at 'spot the difference' :)

I finally managed to get them to work :D though I'm not sure I could tell you how....
Slowly moving the image away from my nose worked for the last one (which I got most quickly); for the others I looked at my reflection which made the image super blurry, then tried to slowly bring it back into focus. Consistency in attempts hasn't been great though, and if I try to "see" them again to pick out more detail, it doesn't always work.

The people sat near me on the train must think I'm a total nutter haha!

A fun thing to try is to make the outline of a cube from thin uniform sticks, paint it in luminous paint, hold it up in front of you in the dark (so you brain no longer has any clues based on shadows, it just sees pure outline). Then us the same sort of technique to flick the image into reverse, so the brain is now interpreting the side nearest you as being the side furthest away. Now try gently moving the cube around. Instant sea-sickness as the brain tries desperately to reconcile what it "knows" about the orientation of the cube with the way the different edges are moving.

Necker cube it's called.

Nope. Nowt. Nada. Zilch. Bugger all.

Althought have just realised I've wasted 5 minutes of my life squinting like a pillock at the computer screen.  o_O

:LOL: :LOL:  Sorry Martin, shouldn't laugh but your comment did make me smile  ;)

Does it make a difference if you are short sighted - I only need glasses for driving and seeing far off things - like the bottom of a shaft getting rapidly closer by the second?  :blink:

I used to wear glasses for caving but usually store my 'caving specs' in the top of my helmet just in case, they would steam up and/or get covered in the finest Derbyshire cave mud.  :yucky:

I'm glad Pegasus likes a laugh, I just can't see whats supposed to be there - unless there isn't anything there and you lot are pulling my plonker..... :spank:

I've just spent a minute or two gazing at Badlad's rope this morning trying to see the 3D image before I realized what it was!    :-[
