2. What is an Illusion?

      • illusion( -l zh n )noun
  • illusions that deceive the human visual system into perceiving something that is not present or incorrectly perceiving what is present.

3. The Human brain put images together because it has learned to expect things; sometimes the data might get a little confused.We may see an illusion because we know what we are expected to see, even though part of a picture or design may not be completely there. The basis of this is in how we perceive things. 4. OPTICAL ILLUSIONS... 5. 6.
