Illusion
of the Month #17: Sept-Oct 2011
Back | Home
|
|
In
this page you can test your visual ability with 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.

You can use the SVI

for free as long as you leave the copyright and

Have
a look at the colored surfaces of the R's...
Two of them are congruent, that is they
coincide exactly when superimposed. Which ones?
|
Solution |
Incredibly,
the green R-shaped surface and the red R-shaped
surface coincide exactly when superimposed! (see
image opposite).
The
edges, the orientation and the perspective of the
letters provide visual cues that strongly influence
our interpretation of the three-dimensional shapes.
