The project is very simple to recreate, and involves the use of a two-way mirror like this one
Raspberry Pi single-board computer, and an old monitor. The project relies upon MagicMirror
an open source smart mirror platform available on GitHub. There are plenty of good tutorials online
demonstrating how to make your own, so I highly recommend giving this project a go – especially if you
have an old, unused monitor lying around which could be put to good use.
