Are the steps heading up or down?
Which direction is the vault door opening?....Inward?
Outward?
How many cubes do you see simultaneously.....watch
for 20-30 seconds
Can you find 10 faces in this picture?
Do you see a rabbit or a duck?
If you follow the movement of the rotating pink dot, the dots will remain only
one color; pink. However if you stare at the black "+ in the center, the moving dots turn to green.
Now, concentrate on the black "+" in the center of
the picture. After a short period, all the pink dots slowly disappear, and all you see is
a single green dot rotating.
There really
is no green dot, and the pink dots don't really disappear.
Hmmm? We know things aren't always black
& white. Are they always pink or green?
