Mandelknot

The Mandelknot Set is a kind of knot that you will only ever find your earphone cable to be tied in when not used for a couple of days. It seems to happen spontaneously despite how carefully you wrap the cable round your hand and place it on the desk.
Loosely based on the Mandelbrot Set, the Mandelknot is by far the most annoying thing on the planet... except perhaps Justin Beiber.... or Katie Price.
