The rotation of each circle movieclip is determined by the colour of the relevant pixels in the Perlin field: rotation = Math.round(bmpData.getPixel(20+i*25, 20+25*j) / 0xFFFFFF * 720); The divisor is used to translate the colour value into a number that is more useful for rotation. Hi Greg,
There is a hidden Perlin noise field in which the offset value is changed every frame. The rotation of each circle movieclip is determined by the colour of the relevant pixels in the Perlin field:

rotation =
Math.round(bmpData.getPixel(20+i*25, 20+25*j) / 0xFFFFFF * 720);

The divisor is used to translate the colour value into a number that is more useful for rotation.
