Optical
Illusion of the Month (October-November 2009)
by
Gianni A. Sarcone and Marie-Jo Waeber
"One’s
own view of reality as
the only reality is the most
dangerous of all delusions."
– Paul Watzlawick
In
this page we will present interactive optical illusion challenges.
Each month, we will post new puzzling illusions to solve and/or
to comtemplate: ambiguous and completion figures, impossible
figures, hidden objects, illusions involving colors, geometric
illusions, illusory moving patterns, verbal illusions and paradoxes.
All these illusions were adapted/designed by the authors with
the aim of allowing the visitor/reader to
• discover how we perceive things,
• test and enhance the power of observation and critical thinking skills,
• improve mental flexibility,
• have fun being deceived by puzzling visual challenges.
