Wall Mirror is a lifestyle Android app developed by Nick Hall. It is a simple app that displays useful information on a tablet that is mounted behind a two-way mirror so that the text appears to float on the surface of the mirror. Wall Mirror is a great conversation piece and genuinely useful. The materials cost around $130.

The app features a fully configurable UI, so you don't have to be a programmer to use it. Just configure it with your location, the stocks you want to track, your nearest bus/train stop, and mount it in a frame. The app includes time, day of the week, birthdays and holidays (configurable), appointments and reminders from your Google Calendar, current temperature, high/low for the day (from forecast.io), and time til your bus/train arrives (takes some technical savvy to set up, but no coding required). The brightness and font sizes are configurable as well.

Instructions on configuring the app can be found on the app's Github page.
