Procrastination.

I am taking part in a "secret friend' swap this year, which means over the course of the year, I stalk someone (in a nice way) and send them things that I think they would like when they need a bit of cheering. Likewise, someone does the same for me. My Secret Friend has been doing some super stalking, and sent me two fabulous gifts from the Discworld Emporium - some bookplates and a Procrastinator.
A Procrastinator allows the user to speed up or slow down time as required. Seeing as I'm back at work this week, it could come in handy, particularly during staff meetings...
