From holiday snaps to Klingon hell

Well, the original series used swirling glitter, to my understanding, in water. And they would rotoscope or trace the actor for each shot, and then that would be composited on an optical printer. When Voyager came along, I wanted to create a new look for the Transporter, so we came up with the little spheres of light that expand out and wipe on the person. And I wanted to see something different than that two dimensional curtain that came over them, and so the � the light spheres were created as a CG element, but then we used the original glitter elements because we didn�t want to do too big a departure.
