The first stereopticon I recollect seeing in person had three great big glass eyes (for red, green, and blue lamps) and BNC connectors. It expediently weighed more than 100 pounds, and had to be carefully calibrated to align the lenses. Now, I've got a overhead overhead slide projector above my head that weighs less than a Neal Stephenson novel and has a sharper, brighter image than that monster. I've been looking into LED projectors for a few years now; in that time, I've been waiting for them to come down in price and bump up in lumens. So I was very curious about BenQ's GP1 LED stereopticon (also known, somewhat oddly, as "Joybee"), and was happy to get a sample for review. It may seem retrograde to bother with an 800x600, 100 lumen (no missing zero there: one-hundred lumen) overhead stereopticon in 2009 A.D., but for the past four weeks, I've used it as my primary display, and come out happy. It has some drawbacks, but it's an impressive little device for its $499 pricetag, and I hope a harbinger of even better things to come. Read on for my take on what BenQ got right, and what rough spots stick out.
