It's an elephant coming at an angle. There are logs on the ground. Can see trump and tusks clearly. Big ears.

It looks like the back end of a horse with the head of the horse looking at me or the viewer.

@Curly - stare by lightly varying both your degree of cross-eyedness (sorry don't know the correct English word =) and distance from the screen. 

Go to the page and try others until one works for you, and usually after seeing one you'll be able to see the others.

Wow that is pretty good - it looks like a 3D horse is teaching Adam and Eve - very impressive.   The people and horse are composed of smaller people and smaller horses.  Amazing!!

Are you good with Stereograms?

It's easy: click to enlarge and just stare cross-eyed =)

Loads more HERE (It beats transcendental meditation IMO.)

The optical illusion videos are interesting Michel.

Scientists' Toughest Nut To Crack

David Barash thinks it's the question of how the brain creates subjective experience:

[T]here are lots of other hard problems, such as the perennial one of reconciling quantum theory with relativity, whether life exists on other planets, how action can occur at a distance (gravity, the attraction of opposite charges), how cells differentiate, and so forth. But in these and other cases, I can at least envisage possible solutions, even though none of mine actually work. But the hard problem of consciousness is so hard that I can’t even imagine what kind of empirical findings would satisfactorily solve it. In fact, I don’t even know what kind of discovery would get us to first base, not to mention a home run.

Seems to me I ran across this some time ago, and then completely forgot about it again. Ran across it again last night, so posting here. Crazy stuff.

 

Alien hand syndrome (also known as anarchic hand or Dr. Strangelove syndrome^[1]) is a neurological disorder in which the afflicted person's hand appears to take on a mind of its own. Alien hand syndrome is best documented in cases where a person has had the two hemispheres of their brain surgically separated, a procedure sometimes used to relieve the symptoms of extreme cases of epilepsy. It also occurs in some cases after other brain surgery, strokes, or infections.

 

A person with alien hand syndrome can feel normal sensation in the hand and leg, but believes that the hand, while still being a part of their body, behaves in a manner that is totally distinct from the sufferer's normal behavior. They lose the 'sense of agency' associated with the purposeful movement of the limb while retaining a sense of 'ownership' of the limb. They feel that they have no control over the movements of the 'alien' hand, but that, instead, the hand has the capability of acting autonomously — i.e., independent of their voluntary control. The hand effectively has 'a will of its own.' "Alien behavior" can be distinguished from reflexive behavior in that the former is flexibly purposive while the latter is obligatory. Sometimes the sufferer will not be aware of what the alien hand is doing until it is brought to his or her attention, or until the hand does something that draws their attention to its behavior.

 

Sufferers of alien hand will often personify the rogue limb, for example believing it to be "possessed" by some intelligent or alien spirit or an entity that they may name or identify. There is a clear distinction between the behaviors of the two hands in which the affected hand is viewed as "wayward" and sometimes "disobedient" and generally out of the realm of their own voluntary control, while the unaffected hand is under normal volitional control. At times, particularly in patients who have sustained damage to the corpus callosum that connects the two cerebral hemispheres (see also split-brain), the hands appear to be acting in opposition to each other. For example, one patient was observed putting a cigarette into her mouth with her intact, 'controlled' hand (her right, dominant hand), following which her alien, non-dominant, left hand came up to grasp the cigarette, pull the cigarette out of her mouth, and toss it away before it could be lit by the controlled, dominant, right hand. The patient then surmised that "I guess 'he' doesn't want me to smoke that cigarette." This type of problem has been termed "intermanual conflict" or "diagonistic Ideomotor apraxia."
