hey, I actually saw the skinny figure *behind* the chubby one, the whole thing
seemed 3-layered.  and I swear in some moment I saw 4 hats in the outer figure!

very nice!

A lot of people I know can't see these things for some reason. The easiest way
is to focus on something further behind image. I tell people to look at the
wall behind the monitor and let their peripheral vision make out the image and
then slowly move focus back to the monitor. After enough training, they can do
it without looking beyond the monitor first.

I will suggestion this technique to my brother. Thanks!

   Incredible... I can't understand where you get all these great ideas... 
surely your mind is unique: you seem to easily come up with techniques for 
things that most of us consider impossible or very hard.

   BTW, I can see stereograms from any distance, and even while walking 
around...  :)

I did a lot of drugs in the sixties (says the guy who was born in the 
late seventies). Seriously though, I really need to actually *finish* a 
scene. Something you seem to be good at... :)

That's pretty good. Reminds me of how I'm always trying to see 3d images 
in repeating patterns, on buildings and posters. I'm always checking 
things, to make sure I'm not being hit with subliminal messages...

Thanks for the input~

Simply brillo!

I am one of those people with great depth perception, but I have great 
difficulty merging regular stereo views.
For this however I got it in short order. My technique was quite different 
to some suggested above:

Get up really close to the monitor.
Stare through it.
Slowly move your head away to about 1 foot moving sightly from side to side 
as you go.
Those edges pop into focus as you go.
Once you have a lock on the 3D picture, its easiest to hold if you keep your 
head moving a little.
At this point you can comfortably retreat to your normal viewing position.

Thanks Sam,

DLM

I thought my depth perception was bad because of watching stereograms 
too much.

that's more or less what works best for me too, except
I stay very close until the eyes adjust a bit and don't
move sideways as it distracts me too much.

First attempt it took me 3 minutes to get it into focus,
which was exactly time for the screen-saver to kick in.
That starfield simulation sure looked odd then ;)

Great Job!

Oh wow! This is the first time in my LIFE I've EVER been able to see one 
of these things. For many years I was actually convinced the whole thing 
was an 'Emporer's new clothes' scam. But using this technique, I've 
FINALLY seen an image inside the mess!

Thankyou!

Cheers!
