How would you make a perfect flicker effect.
I'd use one of these: http://www.gamonline.com/catalog/flickermaster/index.php. ;-)
But since you already have an Express, write an effect that has the same channel(s) in each step with various HI and LO levels and varying IN/DWELL/OUT times. Apply the "RANDOM" attribute. Adjust to taste. Stop when it looks right.
