It looks annoying, like a furry swiss roll on wheels. Even its name is irritating: Clocky. But that's nothing compared with what it does. Clocky is surely the most infuriating wake-up call ever devised.
Dreamt up by a scientist at the Massachusetts Institute of Technology, it works like this: You hit the snooze button because you are desperate for a few more minutes' sleep. Clocky then rolls off the bedside table and wheels around the bedroom floor bumping into things, before settling on a place to hide.
Be afraid, be very afraid.
