Optical Illusion Editor

I did a quick test on Akiyoshi's leaf wave optical illusion by doing some simple scripting (AS3 Flash). I want to know if a rotating pattern will cause more nausea to the viewer. It turn out that fast animation will stop the optical illusion effect. I have upload this is the simple "optical illusion editor" online which you can use the generate your own optical art.

illusory motion, also known as motion illusion, is an optical illusion in which a static image appears to be moving due to the cognitive effects of interacting color contrasts and shape position

Optical Art

Below are some quick results I did using this editor.

Script

The script itself is pretty simple and straight forward. It is just a tilebase map with offset rotation. There are multiple ways to offset the rotation.

for (var i:int = 1; i <= _TILE_X_MAX; i++){
for (var j:int = 1; j <= _TILE_Y_MAX; j++){
_Tile = new Tile();
_Tile.x = i * _TILEWIDTH;
_Tile.y = j * _TILEHEIGHT;
_Tile.rotation =  (j - i) * _ROTATIONOFFSET;
addChild(_Tile);
}
}

The Editor

You can use the editor in my deviantart. This is develop with Flash AS3, so you might not be able to view with your mobile phone.

Warning! This "Illusory motion" optical illusion editor might cause nausea, dizzy or sick. If you start feeling unwell. Please stop using this editor.
