The rental shop doesn't include the red/blue glasses with the rental, which would be included if I were to purchase the DVD. I don't want to dig through the boxes in my garage to find my Lee Filters sample pack. I have red and blue flashlights, from Streamlight <http://www.streamlight.com/stylus_specifications.htm>, readily available. Do you think I will be able to enjoy the 3-d effect if, instead of viewing through red/blue filters, I project red/blue light onto the viewing screen? I am goint to test it this evening, but I wanted to get some knowledgeable hypotheses from the forum regrading the viability of this idea. I have bad news for you. I surmise that your optics textbook was written by Plato, and unfortunately some of his ideas have been found to be wrong. How, exactly, are you going to project this red/blue light?
