I found this in my drawer today. Not used it for a while. I’ve got a Windows Phone Lanyard (tastefully printed with a Windows Phone logo all along its length) to give to the first person to come to my office in Hull and tell me what is and what we used to use it for.

A clue, it is not directly related to phones as such…
