Scary Face Smiley Face

This is really cool and a bit freaky but you might
have to back off a bit, or squint your eyes.

Do you remember the story of Dr. Jekyll and Mr. Hyde?
Dr Jekyll, the famous scientist, is not all he seems,
and the other side of his character - Mr Hyde - is,
you will recall, a distinctly nasty piece of work.

Continuing the idea of the two sides of the human
character, have a look at the picture above. On the
left is Dr Angry, and on the right is Mr Calm.

Now, back away from your computer screen. This effect
will work at different distances for different people,
but you should see the two characters swap over...! As
you come closer to the screen again, they revert to
their original characters. Spooky or what!

As optical illusions go, we think this is pretty
impressive. A short explanation goes something like
this. When we look at an object, we can normally see
both fine detail and coarse detail. However when we
are close, the fine detail will dominate, and when we
are further away, we lose the fine detail, and see
more of the coarse detail.

Both of the faces you see above are hybrids - each
face is actually a combination of two faces. The left
hand face shows an angry man in fine detail, but
within the picture there is also coarse detail of the
calm face. Move away, and you lose the fine (angry)
detail, and just see the coarse (calm) detail.

The right hand face shows the calm face in fine
detail, and the angry face in coarse detail.
