Hi Yi, As long as the code hasn't changed too much from Milkdrop, per vertex variables are, basically, per-pixel equations. They allow for alteration of visuals based on distance from the center of the screen, x-position, y-position, angle, etc. They're called per-vertex as opposed to per-pixel because they are not calculated for every pixel; the values are calculated for every pixel on an X by Y mesh, and then values between are interpolated based on the calculated values to speed up the process. One of the people actually developing the software could probably be a little more specific regarding how this operates on the Milky Mist. Hope that helps,
Nate Semi-unrelated: is there a Flickernoise manual sitting around anywhere? I'd love to get my hands on it...
