Last week Amazon announced several (not so) new concepts. My attention was grabbed by all the fake images associated with the Amazon Glow. The Glow incorporates a small “down projector” (projects down on a surface). I then got curious as to what projector technology Amazon might be using (and will give my best guess). There are so many ways in which the Glow down projector is a flawed concept, and it only has gotten worse with age.
