This application is an educational and instructive tool for understanding Octave of Motion interactively and functionaly.
Diagonal motion occurs when you tap the screen, and it has a function that allows you to interactively change the left and right diagonal stripes with a pinch gesture.
If the left diagonal stripes are half the right (one octave change), the left diagonal motion caused by reversal counter phase is dominant. And if the left diagonal stripes are twice the right (one octave change), the right diagonal motion is dominant. So, the change of one octave makes either left or right motion dominant.
This characteristic of human vision, Octave of Motion, is sure to be useful in various fields such as Visualization, Visual Art & Design, and provides many hints of adequate utility for visualizers, artists, and designers who think different.
