A while back, I sounded off on a new LCD monitor capable of giving 2 differing pictures/movies depending on your viewing position.
Now comes a real handy device, the VisionMirror(tm).
It’s a mirror with an embedded flat-panel monitor/TV.
With the monitor switched off, it appears as a regular mirror.
