Hiding Cat Pictures in Windows

Hiding Images in Plain Sight: The Physics of Magic Windows, in which a guy uses caustics and a bunch of optical calculations to use a CNC router to mill a piece of acrylic to make a clear piece that one can see through (with some waviness), but that projects a cat picture when light is shone through it.

We will not edit your comments. However, we may delete your comments, or cause them to be hidden behind another link, if we feel they detract from the conversation. Commercial plugs are fine, if they are relevant to the conversation, and if you don't try to pretend to be a consumer. Annoying endorsements will be deleted if you're lucky, if you're not a whole bunch of people smarter and more articulate than you will ridicule you, and we will leave such ridicule in place.
