I keep meaning to do this, for probably two decades by now! Just found a bunch of near-new Carousel trays at the dump today and I have a nice projector and screen. Haven't pulled the screen out in years, so condition is unknown. I remember when the kind of screen to buy was a big topic, what type of lenticular, who made it and how much to spend. I remember setting slides shows to music back in high school. Simon & Garfunkel was popular. So when was the last time you set up a traditional "slide show"?
