A while ago I accidentally dropped my Android tablet on its face. The glass broke, but the rest was still working fine. At the risk of being called a hoarder by my partner once again, I put it in a draw, hoping I'll find a use for it some day. That day came when I got a "staff's picks" email from Instructables with a link to this cool Smart Mirror project https://www.instructables.com/id/Android-Motion-Sensing-Smart-Mirror/
