This optical illusion relies on a principle
called "Chromatic Adaptation".
An object may be viewed under various
conditions. For example, it may be
illuminated by the sunlight, the light of a
fire, or a harsh electric light. In all of
these situations, the visual system indicates
that the object has the same color: an apple
always appears red, whether viewed at night
or during the day. This feature of the visual
system is called chromatic adaptation.
Have you ever entered a movie theater on a
sunny afternoon? The room probably appeared
completely dark but as your visual system
adjusted to the reduced level of light you
were able to see better after a few moments.
This "adaptation mechanism" allows our eyes
to recover from an oversensitivity to a
particular stimuli. "Chromatic adaptation"
occurs when our eyes adjust to certain color
stimuli. Chromatic adaptation is one of the
more easily fooled aspects of vision, and is
prone to some of the most spectacular optical
illusions.

| Time Fountain - Optical Illusion |
 |
This device creates the illusion that a
simple stream of water droplets can defy the
known laws of physics. By controlling a set
of flickering LEDs, the dripping water can
appear to slow down, freeze in mid-air, and
even reverse in direction.
This illusion exists because the brain
attempts to fill in the gaps between flashes
with its anticipated motion. It is the same
reason that your brain interprets the 24
frames/second of a movie to be in-motion,
rather than recognizing the individual still
frames .
The credit for this device belongs to Nate
True. You can learn how to build your own
