As well as showing a reflection, it also displays various widgets such as the time, weather etc. The whole thing is powered by a Raspberry Pi which is projected through ‘two way glass’ using a standard monitor. Read all about it here. He uses Chromium in kiosk mode and has uploaded all his code to Github so, if you wanted to, you can reproduce this rather nifty hack.
