Attach a Tile to your keys, wallet or bag and you will never have to look for them again. If you do not know where you put the item, you can make it beep with the Tile app. If it is further from home, it can be located by other Tile users that pick up its signal.

Fulfills some of the whishes I had for the locating technology I set out to create for my HCI class from Coursera.
