PCWorld reports that Philips has announced a new PC or TV display that can be incorporated into a mirror. This would allow you to have a portion of the mirror become a digital display while you are using the rest of the mirror for something else.
The technology will first be marketed to hotels. Philips doesn’t plan on marketing to home customers until around 2005. Fortunately, you could make your own by putting an LCD display behind a 2-way mirror.
