Missing shapes. Optical Illusion.

Missing shapes, phantom shapes or Illusory contours.
These are diferent names for the same optical illusion.  

How many triangles do you see in this picture?

     Phantom shapes are a form of optical illusion where countours are percieved without colour change across the contour. That means that we see a shape that really does not exist.

     These are two simple missing shape optical illusions shown in black and white. The existence of a white triangle can easily be imagined in the top image while your brain can also easily create the existence of a white sphere in the lower image.

Try to find the Star!!!
