Color 2: Available when 2 Color is selected from the Color Type pop-up menu, sets the
second color of the spiral.
Gradient: Available when Gradient is selected from the Color Type pop-up menu, allows
you to pick a gradient from the Library.
Scale: Available when Modern is selected from the Type pop-up menu, determines the
size of the spiral arms.
Tightness: Available when Classic is selected from the Type pop-up menu, determines
the curl of the spiral. The lower the Tightness value, the looser the spiral.
Contrast: Controls the transition between the two colors. A value of 1 creates the highest
contrast between colors; lower values create less contrast, softening the spiral. The Contrast
parameter is not available when Gradient is chosen from the Color Type pop-up menu.
Rotation: Rotates the spiral around its center. (Animate the Rotation parameter to create
a hypnotic effect.)

Star
The Star generator creates a glowing star shape that contains an alpha channel. The scale,
width, angle, epsilon (which fine-tunes the size of the star spikes), and opacity of the
spikes can be modified and keyframed, as well as the position, color, and radius of the
star.
