From: Ron Natalie <ron@brl-bmd> OK GUYS, as long as we're getting nit-picky and since it popped up again for the zillionth time: This complaint has has nothing to do with Lucas or the production of the movie, but rather with the nomenclature used by people on SF-LOVERS when discussing the finer points of these movies. The images of Kenobi, Yoda, and the elder Skywalker that appear after their physical deaths are NOT holograms (as they have been referred to). Holograms are to 3D as photographs are to 2D. These images are based on a much older concept. They are GHOSTS. I guess the readers of this digest are just too technical to grasp such simple concepts. Our laser people tell me that even the projections from Artoo (Leia in the original movie, Luke in the last movie) aren't really holograms as we know them either (but I'm willing to let this slip since technology progresses in unforseen ways). -Ron
