Traveling Without Moving
was inspired by an illusion,
created by Akiyoshi Kitaoka, entitled
"Dongurakokko" (The Donguri Wave).

"Donguri" means acorns, "ko" means a container,
and "domburakokko" means the sound of floats
on a flow of water.

Dr. Kitaoka has extensively studied visual illusions
including geometric illusions, lightness illusions,
color illusions, motion illusions and
stereoscopic illusions.

A 2-dimentional "anomalous motion illusion",
such as these, achieves its effect by exploiting
the way our optical system processes
visual information.

For more information on these effects,
view Dr. Kitaoka's website.

In this experiment, I have utilized one specific color palette of Dr. Kitaoka's, and created a program to generalize a whole class of wave motion illusions, of which
The Donguri Wave is but one instance.

In my version, particles can rotate both along the center of the object as in Dr. Kitaoka's Donguri examples (creating straight-line fields), but can also rotate around a
corner point (creating oscillating-line fields).

Donguri particles are programmed with a randomized
size, rotation angle and spacing distance.
