Defines the x and y coordinates of the center (i.e. focus) point of the galaxy effect.
Defines the lower radius of the galaxy.
Controls the width of the lower end of the spirals.
Controls the angle of the spirals.
Defines the upper radius of the galaxy.
Controls the upper width of the spirals.
Determines the number of full revolutions each arm makes in the given timeframe.
Controls the swell i.e. the amount of time that the head of the spiral uses.
Sets the speed of a non-linear movement for the head color and body.
Reverses the direction of the rotation of the galaxy effect.
Each edge blends to black. Turning it off converts the galaxy effect to a full circle at the end of the rotation.
If the spirals overlap, it determines if the spirals will appear to be moving inward or outward. If there is no overlap, this setting will have no effect.
